Hi
I had the same problems with GRE not passing through to a server behind
the firewall.
I then used kernel 2.4.22 and the latest pom snapshot
(patch-o-matic-20030831) with iptables 1.2.8
and gre passed through.
However, after testing I notice now that although PPTP connections to a
win2000 server behind the
firewall work, that the connection is not reliable. After 3 to 4 minutes
the connection is closed for
some unknown reason and people have to re-establish the connection.
Anyone experiencing this problem also?
Regards
Wim

Hi,
Thanks for your reply re: my problem.
probably the most important thing you can tell me is if I have to appy any
patches or modules in order to make this work. There is a heck of alot of
differing opinions on the various forums and im not sure which way to turn.
I just want to rule this out knowing that it is essentially native in a
standard kernel and it should be just a configuration issue.
Cheers
Jamie

Hi
I made a dump with tcpdump about the problem with pptp connections to a
windows server behind an iptables
firewall that stops working after a few minutes. What I did was make a
connection to the pptp server through
the linux box and then start a ping to the pptp server. Connection
started 17:58:12 and stopped on 18:00:12,
exactly 2 minutes after connecting? Any explanation for this?
My setup as explained below: kernel 2.4.22 and the latest pom snapshot
(patch-o-matic-20030831) with iptables 1.2.8
Attached is the tcpdump log.
Regards
Wim

I had the same problem, and I solved it putting in my options.pptpd
configuration file as follow:
lcp-echo-failure 30
lcp-echo-interval 5
This is to prevent timeouts in the client side, with the
lcp-echo-faliure your server send echo request to the clients for
respons when are an idle time, so you can modify this parameter to a
higher value.
I hope this will solve your problem, well, It was enough for me.
regards.

Jorge
My connection goes to a windows PPTP server behind the linux box, so there
is no options.pptp. Anyway thanks for your answer.
Note that this worked with a 2.2 kernel with ipchains
Regards
Wim
