Title: pptp connects, but can't ping LAN
Post by: Jerry Karn on August 01, 2002, 11:36:30 PM

Hello All,

The odd thing is, this was working a week ago, but I can't figure out what has gone wrong.

I can VPN into my SME (5.1) server from an internet dialup just fine.  Once connected, I can ping the SME server's LAN IP just fine.

But I can't get a ping response from any other PC on the LAN.

Also, the PC's on the LAN cannot ping my vpn client, even though ipconfig shows I have a internal ip.

Any thoughts?  It really seems like the SME server isn't allowing me to communicate with the LAN, but I'm not sure why.

Many, many thanks for anything you all can offer.

-Jerry

Hi Jerry,

Were you trying to ping LAN clients by their NetBIOS names or their IP addresses ?

If you can ping their IP addresses but not their NetBIOS names, then welcome to the wonderful world of SME VPN ! But seriously, this is a WINS issue. For some reason, SME's WINS does not work the way we expect for VPN clients. On some installations, I've had to point VPN clients to a W2K server's WINS server behind SME in order to get name resolution to work correctly. If the number of remote clients is small, you could also manually set the IP addresses for the LAN machines in the local LMHOSTS (or hosts) files.

Not sure about why it worked for you last week but not this week (unless something have changed, which is the likely case - not necessarily a visible change).

I am having the same problem with SME 5.5.

The VPN client connects but is given a 255.255.255.255 subnet mask and can't ping anything but the SME server IP.
