We understand what you want to do (broadly speaking). We've told you that OpenWrt should be able to do everything you want, too. Although you have not answered important questions (such as if you are actually using all the packages you are listing as required), it really doesn't matter anymore.
There are many OpenWrt users who have road-warrior setups and it works really well. I use it that way myself.
You will not get any better answers that what has been already provided to you, except by trying it yourself. You have nothing to lose because this is a reversible process... if you don't like OpenWrt, or if it doesn't meet all your requirements, you can reinstall the vendor firmware.
Just install or (don't), but there is really nothing more that you're going to get out of this thread.
@tom1995 I think a pertinent consideration is that individuals ask specific questions when they encounter specific problems. Your question is too general. Clearly OpenWrt just works on your device. So there will be tons of users who just use it and profit.
I really think you just go ahead and set up OpenWrt on your device and add packages as you need the functionality. And if you encounter any specific issues requiring specific input then you ask on this forum or on IRC and you will get answers very rapidly.
My real experience is that I bought a Huwaei router (B818-263) and then an Asus RT-AX86u router. The manufacturer firmware on both was rather limiting. The Asus device could be run with something called Merlin firmware which unlocks a lot of functionality in the direction of OpenWrt. But OpenWrt goes a lot further in terms of unlocking potential. I ended up returning my Asus and purchasing 3x RT3200's. I put OpenWrt on them and wow - I have been able to do so much on them and found this great community of enthusiasts. The spirit is fantastic and I've been motivated, encouraged and even mentored in terms of working on various projects like 'cake-autorate' to help keep latency low for variable rate links like LTE and Starlink. OpenWrt is ace!
See @tom1995 right now you are stuck (see snake above) on trying to ensure that you won't lose functionality. But let me assure you that you won't. If you find you need something I can assure you that either it exists already (most likely for most items if not everything) or can be recreated. And you'll find things like cake-autorate or VPN policy based routing which you didn't even think or know about before. Extra cool functionality that wasn't even possible with the manufacturer firmware.
Very deep. Since the OP may have blocked me, it may be good to note to them that - everyone here has had this experience, especially if they used the device before converting it to OpenWrt. The OP also noted Tor issues, it seems that they didn't see (or didn't care) I noted that as working here. I assumed they would inquire - but it seems they need a "Silver Bullet" solution that covers tens of packages en masse. Wireguard with Tor also works here, in addition to setting up Wireguard via the LuCI web GUI. Yet, it's still difficult to understand [specifically] what the OP wishes to accomplish. It's good you let them know in a different gentle manner - that they can simply ask specific questions.
Also...I was lost at the 24/7 power example. I'm not sure if the OP is aware of what is/not in control of the software - and that a router running overnight is common.
I get the impression that you do not read my answers))
I specifically highlighted this answer in black for you. Once again, I am attaching the answer here for you personally.
yes, I would like to have all the listed functions, but without the gl interface, which is very slow
As for the choice. Why do you write WE? You can please write an answer from yourself! Or you do not have your own opinion to give an answer and you hide behind the word WE?
As for the answers, once again please answer for yourself, do not speak for others in their answers. The communication scheme is very simple: if you can help, help, if you can't - ok, I don't need your meaningless answers off the topic of the question.
@jdwl1o1 No need to answer for me and think!
I asked a question and if someone can help me to answer (help) I will be very grateful! If not ok, no big deal. No need to write meaningless messages off the topic of the question. You write me a message with some recommendations, please leave it in another place. The topic of my post is not recommendations, but a specific question.
The answers you've been getting are all correct ....
But we're not going to do the leg work for you. Install openwrt, and find out
which packages are needed to provide the functionality you require.
If you expect someone to list them for you .... it's simply not going to happen.
I'm sorry, but that's not how I work. I can’t engage in adventure, especially if it concerns programming or mathematics))
I'm not asking you to do my job, you think it out on your own!
There are no answers, it's okay, I'll wait or I'll look for them myself!
I do... but I am finding that it is a waste of time since you don't appear to be reading (or accepting) the answers the entire community has provided.
Yes, I understand that. But that doesn't answer the question I was asking... are you actively using all of the features you have listed. For example, are you using the USB modem and tethering and MAC Clone and OpenVPN and Wireguard.... are you actually using all of those features. To make a silly example, if you're making chicken, do you use every spice you have in your spice rack? No, of course not... cinnamon would be a rather strange flavor to add alongside basil and red pepper flakes.
Having features available is not the same as actively using them... that's what I was tying to get to.
We the community. I like to acknowledge the other fantastic contributors in this forum, many of whom have added comments into this thread already. While I cannot, and do not, speak for them, I include them as one does in the context of a team effort.
Oh, I most certainly do have my own opinion. And my opinion is that you are wasting everyone's time and that you are probably a hopeless case.
Echoing what many have already voiced... just install OpenWrt and install/configure your required packages. Then ask specific questions if/when you run into problems. Asking a series of very general questions and dismissing the answers you get from many different users just isn't a going to be useful.
I'm interested in this from a psychological perspective. So if I understand correctly you want to have every last detail mapped out in your mind before proceeding. Is that owing to a fear of the unknown? Or is it because there is some form of enjoyment out of planning to such depth in advance? Or something else?
One problem you face with this approach is that you don't know what you need until later through use. New things will crop up along the way. And things change with time. Consider the huge change from iptables to nftables.
Software is not static and constantly changes and gets updated. So even if you plan everything, the plan will become invalid in only a short time.
I mean consider the manufacturer firmware which you seem anxious to reproduce as much as possible despite this excellent example:
That will change with time too. Even if you manage to find a plan P(T1) to recreate firmware at time T1, F(T1), then the problem is that F(T2) is not equal to F(T1) and then your plan P(T1) will not work for F(T2).
So this approach is really not going to work and you really do need to set up some dynamic capability here. OpenWrt is a highly dynamic and non-static entity. So only a dynamic approach is going to work.
@psherman Thank you for your reply.
Gl-e750 is not a chicken but a complex technical device, how much do you know portable 4G LTE with such functions on OpenWRT ?? (not usb, not powered)
Please write here. After you research this question, you will understand the answer to your question about why all these functions that I wrote are needed. I want to note that I wrote some of the functions from those installed by default in GL-E750 !
If you read the documentation, you will see that there are more functions there!
Have you ever thought that the words and thoughts of a person are just like open source, the smaller and clearer it is, the better it is, for example SUDO and DOAS))
As for my question. You and many here who write that I don't know what I want is a 100% mistake! Before writing a post here, I used this device, unlike you, for a certain time, I understand its capabilities and understood what I need, so I wrote a list (see above)
Given that at the moment I do not teach the answers I need, I will have to independently investigate this issue.
