Ok. I took us a bit, but we are now running kernel 2.6.9-34.0.1.EL.
We seem to be having the same problem in that the GRE header is not
getting stripped off (squid is not getting the packets).
My gre tunnel is:
[EMAIL PROTECTED] squid]# iptunnel
sit0: ipv6/ip remote any local any ttl 64 nopmtudisc
gre0: gre/ip remote any local any ttl inherit nopmtudisc
gre1: gre/ip remote 10.2.0.1 local 10.2.0.10 dev eth0 ttl inherit
During a trace, I see the packets being sent from the loopback
address of the router, but the proxy is not replying.
Also, my gre interface shows:
[EMAIL PROTECTED] squid]# ifconfig gre1
gre1 Link encap:UNSPEC HWaddr
0A-02-00-0A-00-00-00-00-00-00-00-00-00-00-00-00
inet addr:127.0.0.2 P-t-P:127.0.0.2 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MTU:1476 Metric:1

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
No packets to or from the gre interface.
Any ideas?
Thanks

Sorry, I should have stated that. We are using kernel 2.4.21-37.EL.
The ip_gre module is loaded.

We are using squid (Version 2.5.STABLE14+module1.0) with WCCP v2
compiled in to transparently redirect http. The problem seems to be
that the GRE headers are not being removed. The access log does not
show incoming requests. The tcpdump trace shows that the GRE packets
are being sent to the cache server, but no packets are flowing from
the server.
Any ideas as to what we are doing wrong?
