VPN Tunnel

We have a VPN 3005 Concentrator. One of my users is using Netvanta 3448 from Adtran. When he connects through VPN client, he can't access his internal network (printers, file sharing, etc.) What can he do so he can access his internal network while connecting through VPN? Thanks.

Re: VPN Tunnel

Diane,

One of two things is possibly happening:-

1) The VPN profile is configured to encrypt all traffic.

2) You have configured split-tunneling, but the users LAN is the same subnet as the encrypted LAN.

Check you configuration on the 3005 - and ask the remote user what LAN IP Subnet they are using.

HTH.

We have configured Split Tunneling on the VPN Concentrator. The remote user is using the private IP address of 172.31.

Thanks.

Re: VPN Tunnel

What IP subnet are you allowing him to view over the VPN?

Re: VPN Tunnel

When remote users connect through VPN successfully, the IP address is assigned by the VPN Concentrator. The IP address is 169.230.XXX.XXX.

Thanks.

Re: VPN Tunnel

I understand that - what IP address is allocated to the remote VPN users?? What is the internal ip subnet range they are allocated via DHCP from the concentrator?

Re: VPN Tunnel

The internal IP addresses from DHCP from the Concentrator are from 169.230.251.100 to 169.230.251.200.

Thanks.

Re: VPN Tunnel

OK - so I am presuming that you have split tunneling enabled on the VPN concentrator? I am also assuming that the network ACL you have defined for the split tunnel does NOT contain 172.31.0.0/24 ??

Re: VPN Tunnel

You are correct. Thanks.

Re: VPN Tunnel

From all the information you have provided - he should be able to use his LAN. Can you get the VPN client logs from the user ands post - this would help to track down the issue?

Diane,

Check out this link:

Make sure Allow Local LAN Access is checked at the VPN client.
