What a beautiful world this could be if we would not get assumptions but
facts. Please get some hard facts on your failures, e.g. let us know
your exact configuration (including addresses of the networks in question).
If you want to disguise them, do it consistently, please.
Please also add tcpdump snippets or even better files for us to analyze
of all interfaces (including tun interfaces) with reasonable timestamps.
We, or rather you, need to know where a packet comes from, where it is
supposed to go and which way it is supposed to take. A little bit of
ascii art is fine, but often the details only tell the whole story. And
while we're at it, please also include the configs and routing tables
before and after the tunnel got up.
Most of the time these problems stem from either routing or firewalling
misconfiguration. It is very possible that you find the reason yourself
while preparing all the information for the list.

Oh there is, (most of the time at least :-) ) the collective knowledge
in this list is amazing.
Good luck
