[pptp-server] unusual problems...

[Chris Mitchell]

gday, 

im using poptop on a rh6.2 boxen, i followed the instructions at http://www.vibres.com/pptpd/example.html, and everything *looks* okay, the box is running samba etc. i can connect to the VPN server from a windows client.....i can ping the upstream side, with pings of about 75ms, however trying to ping from the server to the client results in....not much at all, an example:

PING 192.168.0.202 (192.168.0.202) from 192.168.0.200 : 56(84) bytes of data.
64 bytes from 192.168.0.202: icmp_seq=0 ttl=128 time=76.5 ms
64 bytes from 192.168.0.202: icmp_seq=1 ttl=128 time=74000.7 ms
64 bytes from 192.168.0.202: icmp_seq=2 ttl=128 time=148000.6 ms

thats pinging from the server to the client, whereas client to server goes a little something like:

Pinging 192.168.0.200 with 32 bytes of data:

Reply from 192.168.0.200: bytes=32 time=60ms TTL=255

i do not have any idea what the problem is.......connection attempts look successful: example

ct 12 22:16:16 wollongong pppd[4697]: pppd 2.3.11 started by root, uid 0
Oct 12 22:16:16 wollongong pppd[4697]: Using interface ppp1

Oct 12 22:16:17 wollongong pptpd[4696]: CTRL: Ignored a SET LINK INFO packet with real ACCMs!
Oct 12 22:16:17 wollongong pppd[4697]: MSCHAP-v2 peer authentication succeeded for chris
Oct 12 22:16:17 wollongong pppd[4697]: found interface eth0 for proxy arp
Oct 12 22:16:17 wollongong pppd[4697]: local  IP address 192.168.0.200
Oct 12 22:16:17 wollongong pppd[4697]: remote IP address 192.168.0.202
Oct 12 22:16:17 wollongong pppd[4697]: MPPE 128 bit, stateless compression enabled



it proxyarps and everything, but pinging anything except 200 results in nothing, browsing does not function either.....this is something i havent come across before and ive installed poptop a few times. by the same token, there is also a lot of stuff that i dont remember seeing in my logs before, stuff that looks a little something like this:

Oct 12 22:12:08 wollongong pptpd[4346]: Buffering out-of-order packet; got 327 after 325
Oct 12 22:12:40 wollongong pptpd[4346]: Buffering out-of-order packet; got 359 after 357
Oct 12 22:12:41 wollongong pptpd[4346]: Packet reorder timeout waiting for 358
Oct 12 22:12:41 wollongong pptpd[4346]: Buffering out-of-order packet; got 360 after 358

anyone else had this problem? i can supply other config details upon request, however, they're basically cut'n'pastes from the above URL

cheers, 

Chris
