Hey guys, my parents recieved a new modem from AT&T so I need to reconfigure their network.
The old setup was an Arris surfboard as a modem connected to a Linksys WRT1900ACV2 which had ip 192.168.1.1.
The new modem is a AT&T Arris BGW210 combo modem/router. I had to manually configure it into bridge mode doing the following:
- change modem ip to difference subnet setting it to 192.168.2.254 originally from 192.168.1.254
- disable both firewall and packet filtering
- set IP Passthrough to the MAC of my router
- disabled modems radios
I then plugged my router into the modem with factory settings (DHCP and an ip of 192.168.1.1). While DHCP seems to work I cannot properly access or ping the modem in my network. So I checked the DHCP address and it was incorrect. The modems wan is (99.x.x.x).
So I flashed open WRT on the router but ran into snags. How do I configure OpenWRT with my setup?
Current OpenWRT Settings:
Interfaces:
Lan: static ip at 192.168.1
Wan: DHCP client with correct MAC address (no ipv4 address but I believe this should show up as 192.168.2.254 as I had configured before)
Routes
lan at target 192.168.1.0/24
nothing else. I believe route should have wan but I’m unsure what it should be. I know I can ssh into the router then vim
into /etc/config/network
and edit the route config there to something like
// in etc/config/network
config route
option interface ‘wan’
option target ‘192.168.2.0/32’
option gateway ‘192.168.2.254’
Any suggestions welcome! Thanks in advanced
