there is a lot of really strange (and wrong) stuff in these config files. Where did they come from? Did you edit them?

I would not recommend use Zuxel switch like only one while make such settings
Why don't you use luci, luci is easiest and faster interface for config like this

No you asked for what was in the files now. This was an already configured setup.

45

Why not? An x86 system usually has the ability to connect a display and keyboard, so even if the network is misonfigured, access should still be possible. And aside from one potential setting, I don't see any issue with the zyxel switch.

If you know exactly what to do yes, otherwise no

I'm really confused. I thought you were starting fresh.

No, but I know enough to edit and make the appropriate changes if i can just figure out how to list the ports for the switch.

49

I have an idea, you connect to my desctop, and I start gns3 and we can all check before applaing, so u can see what to do and I can remember how to make it

Well, there are a lot of things there that probably should be revisited... but the VLANs are really simple.

change the ports here to eth0.10

and change this one to eth0.20 (eth1, I assume, is the USB adapter).

so something basic like this.

config device
        option name 'br-lan'
        option type 'bridge'
        option rpfilter 'loose'
        option acceptlocal '1'
        option stp '1'
        option igmp_snooping '1'
        option promisc '1'
        list ports 'eth0.10'

config interface 'lan'
        option proto 'static'
        option device 'br-lan'
        option ip6ifaceid '::bad'
        list ipaddr '192.168.1.1/24'
        option ip6assign '64'
        option ip6hint '0'
        option ip6class 'local'

config interface 'modem'
        option proto 'static'
        option device '@wan'
        option ipaddr '192.168.100.2'
        option netmask '255.255.255.0'
        option delegate '0'

config interface 'wan'
        option proto 'dhcp'
        option device 'eth0.20'
        option broadcast '1'
        option delegate '0'
        option hostname '*'

config interface 'wan6'
        option proto 'dhcpv6'
        option device 'eth0.20'
        option reqaddress 'try'
        option sourcefilter '0'
        option reqprefix '60'

config route6
        option source '::'
        option target '::/0'
        option interface 'wan6'

yup... give that a shot.

do you mind glancing over the settings here and telling me if it looks like i might need to adjust something

For example, I didnt know whether I should enable VLAN trunk for anything,

The only thing that might be wrong with the switch is that you might need to set port 3 as a trunk (in some switches, it is implicit, but there seems to be an option to set it explicitly in that one).

Otherwise, the switch config looks fine based on what I can see.

The OpenWrt config, OTOH, has a lot of things that are either wrong or should only be used if you have a specific reason to.... and there is a lot there to review. I noticed that the DHCP server is setup incorrectly, among other things. But for all the unusual settings that I see, maybe you have them there for a reason.

would you say port 3 explicitely or 3 -24 as trunk.

57

u need 1 trank port and 1 port for wan untaged vlan and others for lan vlan untag

port 3 is clearly the one that should be the trunk.... I don't think you want any other ports trunked in this context.

59

first and last usually reserved for tranks

You mean like port 1 and port 24? That's not necessarily true. I mean, sure, can be a good option, especially if one of those ports is used for connection to the router and the other for linking to another downstream switch, but is not a rule of thumb or standard practice... any ports can be used for any purpose, so it really comes down to what is connected to each port.
