usage:

Flash to router, upload bridgemode template config via config backup/restore, then login as root over ssh/serial (login as admin and get root's hash from /etc/passwd and crack it - md5crypt hash, 8 hex bytes (lower case), really easy on a gpu). Once in, use "ip link dev set mtu 1508" for eth0-eth3, eth0.0-eth3.0, atm0, atm0.2, and br0 to set mtu, and try running your PPP client at 1500 payload. It should work.
