Routing & PPTP (VPN) issue
« on: May 13, 2003, 06:12:29 PM »
Hi,

Still strugeling with a unrealiable VPN connection to several different 5.6U4 servers. 1 server is working fine, the rest not.

Now the difference between the working VPN connection and the failing onces is my local PC (winxp) routing table during connection time....

This is the normal routing table: (simpel)

Address      netmask      gateway      Interface      Metric
0.0.0.0      0.0.0.0      192.168.2.1      192.168.2.65   20
127.0.0.0      255.0.0.0      127.0.0.0      127.0.0.1      1   
192.168.2.0      255.255.255.0   192.168.2.65   192.168.2.65   20
default gateway   192.168.2.1


(x.x.x.x = scrambled remote public IP)
This is during a good VPN connection: (VPN remote net 192.168.20.0/32)

Address      netmask      gateway      Interface      Metric
0.0.0.0      0.0.0.0      192.168.2.1      192.168.2.65   21
0.0.0.0      0.0.0.0      192.168.20.197   192.168.20.197   1
x.x.x.x      255.255.255.255   192.168.2.1      192.168.2.65   20
127.0.0.0      255.0.0.0      127.0.0.0      127.0.0.1      1   
192.168.2.0      255.255.255.0   192.168.2.65   192.168.2.65   20
default gateway   192.168.20.197

This is during a _bad_ VPN connection: (VPN remote net 192.168.21.0/32)
Address      netmask      gateway      Interface      Metric
0.0.0.0      0.0.0.0      192.168.2.1      192.168.2.65   20
x.x.x.x      255.255.255.255   192.168.2.1      192.168.2.65   20
127.0.0.0      255.0.0.0      127.0.0.0      127.0.0.1      1   
192.168.2.0      255.255.255.0   192.168.2.65   192.168.2.65   20
default gateway   192.168.2.1

As you can see it does not have a second default route to the remote local net!

I looked at the options.pptpd files on all server but see no difference.
So I'm trying to locate the origin of the difference.

Does anybody have any clue / hint tips? All appreciated.

TIA

Sorry to waste your time with the previous posting. It seems that the úse remote dns' option for this connection was disabled.

Sorry for the rumble.

An item of note about the checkbox in the PPTP setup labelled "Use Default Gateway on remote network" - I always uncheck it because I'm such a "multi-tasker" and I really don't want ALL my traffic (web, ftp, ssh, external mail, etc, etc.) going through my remote workplace's overloaded net connection.

Also, I wouldn't like to trouble them with strange un-work related entries in their "where have our employees been online today?" log.
