Well I thought that rp_filter was the problem, but the tunnel still does
not work.

On the CIP it see the following;

[netstat]
The client shows SYN_SENT:
tcp        0      1 24.50.39.151:58074      12.33.101.154:80 SYN_SENT   1210    
   1440656    

[tcpdump]
10:07:54.366747 IP ts.gam3.net.58074 > 12.33.101.154.www: S

0,nop,wscale 2>

But on the ethernet I am seeing the ACK:

10:07:54.425890 IP 12.33.101.154.www > ts.gam3.net.58074: S 
3100274228:3100274228(0) ack 3759506183 win 5792 <mss 1460,sackOK,timestamp 
745934204 65544350,nop,wscale 0>

But instead of making the connect the client sends a reset.

10:07:54.425989 IP ts.gam3.net.58074 > 12.33.101.154.www: R 
3759506183:3759506183(0) win 0

Can anyone think of what might cause this.  Or give me some hints on how
to debug it.

Thanks,

Allen Morris
