Hey all,

For some reason there is one PC on a network that I cannot VPN to no matter what. It works fine on wired lan but not over VPN.

What things can I check to acquire access to this PC? What TCP/IP settings need to be enabled?

I am not using a firewall on the PC that I am trying to connect to. It is behind a Juniper SSG140 VPN Firewall.

Any tips you have, even if they seem minimal and insignificant may help.

Thanks!!!

ps. I have tried to VPN from over three machines, and this one PC is not accessible from all three. It is something on the PC itself...just can't figure out what it might be. Or where to start troubleshooting for that matter.

From where are you trying to VPN? Are you trying to VPN into the Juniper Firewall then trying to access this particular PC? Are you trying to establish a VPN tunnel directly to this particular PC?

What settings on the host PC need to be set? (the one I am trying to connect to)

Since you're using the firewall as your VPN server, you need to make sure the one PC you cannot reach has a route or default gateway set to the internal IP of the Juniper firewall. Remote VPN clients will typically be assigned an IP configured in a pool of addresses for the VPN connection. Many network admins will use a different internal IP pool to differentiate device on the network from each other. I know I do this to make keep track of remote and local devices plus to aid in easy reviews of logs.

You were right on the money with the gateway being incorrect!

Thanks a ton z!
