Subject: Routing across CIPE adpaters.

I don't know if this question has been asked before or not (I have searched
the archives - hopefully with the right key words - but have not found an
answer)  I have 3 networks linked together by CIPE:

Network 1  <-----CIPE-----> Network 2 <-----CIPE-----> Network 3

I can route between Network 1 and Network 2 without any problems
I can route between Network 2 and Network 3 without any problems 

My problem is 1 to 3 and vice versa. Also noting that the CIPE Server On net
2 hosts multiple clients on a win32 platform. They have a problem seeing the
remote networks across the cipe tunnels (1 and 3) as well. I am hoping it is
just a route problem and not an issue of routing between cipe adpaters. 

My first question is "are there problems routing across cipe adapters (in on
1 cipe adapter routing to another cipe adpater)"?
If the answer is no, "do I have a problem in my route tables below"?
Here are my route tables:

I use IPTABLES to block all unwanted traffic from the outside and allow the
adpaters to forward all.  If you would like to see those rules I will send
them to you. All adapters use a different IP address, port #, and key...
Any information would be helpful.

Thanks in advance..
Doug
