There are no firewall rules that are specific to the IPSec tunnels.

and no rules specific to ICMP?

This, combined with the fact that small data transfer sessions
across the IPSec tunnels work but small ones don't lead me to believe
this could be a PMTU issue within the IPSec tunnel.

can you start trying with ping -s 1000 and going up to see when it
starts to fail? Try to find out exactly.

Also could you post the relevant netstat -rnW output?
