What kind of packets in particular are failing to route? Have you determined this using ICMP, or is it only with TCP connections? The reason I ask is that this sounds like the dreaded path MTU discovery problem where intermediate routers for certain destinations fail to be helpful (there's a solution involving clamping the MTU with iptables, but google is far more eloquent than I could ever be).

At least TCP and ICMP (ping) are affected. I tend to notice when TCP stops working.
