Julian, I'm pretty sure that we can safely leave the T1 lines out of the equation since both T1s go to the same ISP from different locations. I suspect the problem is on the PPPoE (running Netgraph PPPoE) side because none of the IPSec packets actually go out from the tun0 device when I sniff the network. The PPPoE alone works fine and dandy, and I have set the MTU to 1492 for tun0 and both the internal and external NICs. The ADSL connection is through Bell Nexxia. I don't know if this gives you enough information about my setup, but if you'd like to know more details, I can draw the network diagram between the T1 site and the ADSL site. Thank you for your help.
