(My ISP provides me with a static IP/mask, the gateway seems to change between between 1 or two addresses - Also, I'm in the UK and have to connect via PPPoA, which makes things more complicated ) I have a WRT54GL running Tomato 1.06 which assigns connected PCs addresses in the range of 192.168.1.x in the mask 255.255.255.0. I have a Zoom X3 modem in half-bridge mode attached to the WRTs WAN port, with an IP address of 10.0.0.2 In order to access the configuration of that I have this within the WAN UP script section in Tomato: ip addr add 10.0.0.1/24 dev vlan1 brd + /usr/sbin/iptables -I POSTROUTING -t nat -o vlan1 -d 10.0.0.0/24 -j MASQUERADE Tomato on the WRT is set to pick get the WAN details via DHCP and it correctly displays: IP: 83.67.xx.xxx Mask: 255.0.0.0 Gateway: 194.106.xx.xxx However, PCs connected to the WRT cannot see the internet. If I connect a PC directly into the X3, the PC is assigned the correct values for IP, mask and gateway from my ISP and I can access the internet - this lead my to try cloning a PCs MAC onto the WRTs WAN port, this didn't help. Over on a forum a user suggested it could be a DNS issue so on the X3 I set up the following DNS servers: 220.127.116.11 (OpenDNS) 18.104.22.168 (ISP) and in Tomato: 10.0.0.2 (the X3) 22.214.171.124 126.96.36.199 I still couldn't access the internet. However I did eventually notice a few other IP addresses listed for the Vlan on the WRT; this IP addresses were: 83.26.xx.xx 83.100.xx.xx 83.128.xx.xx a similar range to the IP address that my ISP assigns me using cmd.exe I was able to tracert and ping these IP, however I still could not access the internet. I've been trying to find solution to this for the last week or so now and it's driving me insane One other thing, before I purchased the X3 I was using a Safecom SAMR-4112 modem in half-bridge mode (which is apparently built on the same (similar) conexant hardware) and had no problems at all. I didn't even need the WAN UP script, the WRT found the modem configuration at 10.0.0.2 without any issues - sadly that modem blew up and I can't find stock anywhere, so I had to get the X3 - not many modems seem to do PPPoA in half-bridge mode Could this be a tomato issue or just hardware?
