VPN concentrator 3005 Remote Access

Answered Question

I have inherited 2 VPN 3005's one is in production with a weird config, probably because whoever set it up was having a similar issue. The other I am trying to setup properly and will then move the users to it. It has a public IP and the private port has an address on the local network. I have setup a pool with a different subnet. My client connects but, cannot get on the local network. I can ping the local interface of the 3005 but, nothing past that.

Thanks,

Eric

I have this problem too.

Hi,

If I understand correctly, the tunnel is establishing properly (so no problem on the VPN config).

If you check under Monitoring | Sessions do you see the remote access session established? Also do you see packets received/transmitted?

I would check that the internal LAN has a default gateway pointing to the internal IP of the concentrator (or at least a route to get to it) to be able to send packets back to the VPN clients.

You are correct that, I do not have the route in my default gateway. I do not want to make changes to the gateway during business hours. i have setup a pc on the network with it's GW set to the private IP of the concentrator. When I am connected to the VPN, I cannot ping the PC on the network. The PC on the network can ping the VPN PC's virtual interface.

Ok.

If you have an internal PC with the gateway set to the internal IP of the concentrator that's ok.

The VPN client should connect to the concentrator (you should see the session established fine Monitoring | Session)

When you send packets from the VPN client to the internal PC do you see packets encrypted/decrypted?

Check that there's no Firewall (windows firewall) enabled on the PC preventing PINGs.
