internal network access via vpn


G

Guest

Hi,
I cannot access my internal network when establishing a vpn connection.
I can connect to the RRAS server and get authenticated, but I can't access
anything on my internal network either by pinging the ip's or trying terminal
services. I can get to the internal network from the RRAS server. I have
route statements in for the internal network.

My setup is a 2003 RRAS server with 2 NIC's, one in my DMZ (a dumb hub)
and one on my LAN (Cisco Switch).

My VPN client's ipconfig looks like this:

Autoconfiguration IP Address : 192.168.10.7
Subnet Mask : 255.255.255.255
Default Gateway : 192.168.10.7
DNS Servers : 198.148.164.129

how did you setup VPN? Have you enabled the NAT? this may help, quoted from http://www.chicagotech.net/routingissuesonvpn.htm
Can ping VPN server only but not other resources

Symptom: after establishing VPN, you can ping and access the VPN server, but not other servers and the network resources.

Cause: 1. incorrect NAT/Firewall settings.
2. ISA/Proxy blocking.
3. Disable IP routing/forwarding.


Don't send e-mail or reply to me except you need consulting services. Posting on MS newsgroup will benefit all readers and you may get more help.
