Can someone please tell me how to setup a route when using pptp.

the route command does not seem to help me, and I do not have a nat kernel module, so iptables is also not helping me.


Suggestions? Pointers?

I connect and get an ip address, but I can not use it at all, no packets seem to be flowing?

Can anyone point me anywhere, I need routing help or a nat kernel module. Am I really going to have to break down and install scratchbox and compile the kernel?

Someone must have this, can you please post it?

Thanks

You should be able at least to ping the other side of the tunnel no matter how routing is set. If packets are really not flowing NAT will not help you with this. Last time I tried PPTP it worked for me. For accessing other machines behind tunnel I needed to add specific routes to these hosts or set default gateway (route add default gw x.x.x.x where x is the other side of the tunnel).

Please note this is accurate, but the names and IP addresses have been changed to protect the innocent... ;-)

Any ideas you can suggest would be great !! Sorry so long :-(

__________________________________________________ _____

You can see I setup the default route but it does not matter because I can not ping 139.108.201.82

Nothing seems to be working, I can not even ping the other end of the tunnel

Below is the debug from my connection, it all looks ok, there is the one proxy arp error is this something to worry about?

If you can configure also other side of the tunnel, I'd try to have both IPs from same network but it probably doesn't matter. Also I'd remove 'proxyarp' which IMO should be on the other side of the tunnel if you want to access other computers in remote network since it should pretend your IP is him to computers in that network. But both options should not be fatal. Can you also try to ping your n770 from the other side?

I'd guess it can be also misconfiguration on the other side. I'll try to connect via PPTP too and attach a log.

Also when seeing 'pty' in the output there is a low limit on the number of ptys being 4 so try to increase it just in case

I am connecting to a windows server and I have no access to it. I can connect in windows no problem. It could be something stupid, but I can t seem to find it, I spent a day trying to get my chap file right :-)

thanks for the pty link, that was annoying

I installed syslog and got this output, not sure if this is good or not? there is some nokia ppp autoconf stuff, not sure if this is normal.
