Hi,
I need to start two PPTP connections from my gateway (using two login
names for the remote end) and it does not want to work - both channels open,
but they mix the packets they receive from the server and reject them:
Mar 22 18:12:00 gate pptp[140]: anon log[decaps_gre:pptp_gre.c:362]:
discarding duplicate or old packet 26 (expecting 57)
rcvd [proto=0xf4f8] 4b da 5e 22 f0 53 b5 6a 52 3b 3f 20 c8 64 c2 a2 0a d2 62
e4 65 1f a1 25 16 7a ec 53 4f 40 57 5f ...
Unsupported protocol 0xf4f8 received

a2 0a d2 62 e4 65 1f a1 25 16 7a ec 53 4f 40 ...]
Given the fact that the server accepts both connections if there is a
way for my gateway to distinguish between them things should work. And in
VPN-Masquerade 'howto' it's written that there is an option 'PPTP Call ID
masquerade' that may be helpfull for this. However, this is probably a kernel
patch that I do not know where to find. I get some patches from
http://cvs.netfilter.org/netfilter-extensions/helpers/pptp/, but they give too
much compilation errors - probably a work in progress.
So, may someone point me how to make two simultaneous PPTP connections
work from my gateway to the same server, and if there is a patch where I may
find it?
Thanks, George.
