xbox 360 and wireless ethernet bridge - MTU and ICMP errors

    I have one E3000 running Tomato 1.28 in wireless AP mode and connected to the WAN modem, and a WRT54GS running Tomato 1.28 in wireless bridged mode. I can connect a laptop by wire to a WRT54GS port and it connects to the internet through the E3000, can see all other PC's and printers on the local network. When the xbox 360 is connected by wire to the WRT54GS, the <Test Xbox LIVE Connection> test fails, always with either "ICMP Error" or "MTU Error". "Respond to ICMP ping" is enabled on both routers. Ports 88 (UDP) and 3074 (UDP and TCP) are forwarded from the E3000 to the xbox IP address. The xbox MAC is used for static DHCP in the E3000 so the xbox always gets the same IP. The xbox is set to get its IP and gateway and DNS dynamically, and it does acquire the correct IP address for itself from the E3000 static table, the IP of the E3000 for its gateway, and two opendns IP's from the E3000 for its DNS. By the way, xbox <Test PC Connection> does list networked PC's.

    Any ideas what's wrong?

    Many videos on youtube clear this problem for you they helped my brother many times with this issue.

    Didn't find anything on youtube other than the obvious, like set the MTU to at least 1364, and nothing useful to explain the ICMP error.

    I have also done this but with ddwrt. I would give my bridged router a static ip and use basic dhcp for my xbox. I wouldnt assign a static one, then the bridged router did the rest. I would disable firewall on my client router and all would work well.

    One weird thing I notice. From a PC wired to the AP+WAN router, ping another PC on the wireless ethernet bridge router that has port 80 forwarded to it, the ping resolves to the external internet IP rather than the intraweb IP. Example - the web server is 192.168.0.101, and "ping -t web_server" resolves to a 67.65.xxx.yyy address and not 192.168.0.101 (where 67.65.xxx.yyy is the WWW address). Presumably there is a setting on the AP+WAN router to fix that, maybe one of the Advanced...Routing options??

    Nothing changed in the routers, but I went back to try xbox today and it passed "test xbox live" and prompted to download an update. I have no idea why it wouldn't work before and why it does now. I still have the problem with ping and VNC etc. from a wireless laptop to a PC on the wireless bridged router using the internet IP instead of the LAN IP. Regardless, I'm thrilled the xbox works as a wireless bridge now and I will give the router to my son for his bedroom xbox.
