I have set up a guest wlan according to this guide: https://wiki.openwrt.org/doc/recipes/guest-wlan
Everything works. Now I wanted to create a firewall rule to allow guests to use my chromecast. Unfortunately, it doesn't work.
The rule looks like this:
option target 'ACCEPT'
option src 'guest'
option dest 'lan'
option name 'Allow Guest -> Chromecast'
option dest_ip '192.168.0.207'
option enabled '1'
option target 'ACCEPT'
option src 'lan'
option dest 'guest'
option name 'Allow Chromecast -> Guest'
To be honest, this is my first attempt to create a firewall rule. Can someone help me?
Doesn't it work maybe because the guests have a different IP address range?
LAN: 192.168.0. x
Guest WLAN: 192.168.100. x
If you gave us a better overview of your network, it will be easier to help you.
Isn't easier to connect the Chromecast to the guest wlan when needed?
This is my dhcp and firewall config
and this my network and wireless config
Then I have to connect to the guest wlan as well. It's no a good solution.
HI, have you found a solution?
I was thinking of nating chromecast to an IP on the guest network from your main one.
ex. you assign a static lease to your chromecast on your main network, say 192.168.0.100, and then nat it to, say 192.168.100.100 (must be out of the dhcp range but in the same subnet), on your guest network. This way it is reachable from both the networks.
I have the same problem and I'm struggling to find a working solution.
@artioni81 did you succeed with your proposed solution?
If so could' you share it?
If this is the case, it's only a limitation of the device's software.
To confirm, that is an IPv4-Any rule to 192.168.0.207, correct?
If not an Any rule, have you tested an ICMP Echo-Request rule to a device in 192.168.0.x?
If not an Any rule, have you opened forwarding to all ports needed?
Can you ping the Chromecast on the secure LAN from the Guest LAN?
I googled a bit :>
chromecast uses the following ports
udp 1900 188.8.131.52
the dlna broadcasts needs to be routed between the networks,
i use smcroute for this.
The ttl of the broadcasts also must be increased by +1.
How do I put this data in OpenWRT?
How do I put this data
Did you install
smcroute if you're attempting to relay multicast?
(BTW, you have a similar post here.)
I have two subnets ("lan" and "guest") and I want the guests to be able to send content to the Chromecast that is connected to the "lan" network.
A user directed me to this topic.
I know I did, for one. And I also:
Asked did you install
smcroute first? I also reminded you that you had your original topic open. Simply pick one.
I did not realize it was you. I already installed the package. Now what do I do?
Could you give me some example command to be able to adapt to my network?
Honestly, I cannot. This is why I linked you this thread and provided the instructions. Perhaps
@shm0 can elaborate, as he is the one who suggested this software:
Then I see how I configure it, without first having read the website.
