Cannot see LAN on Windows 2008 R2 OpenVPN Server

escaglj

I am currently trying to setup a new OpenVPN server on a Windows 2008 R2 box. We have an existing OpenVPN server using Windows XP that works fine, but we will be taking that box offline soon. I basically used the same configs, ca, and key files from the old box. I am able to establish a VPN connection from client to server without issue, but I cannot browse the server side network. The routes are there, I'm also allowing UDP 1194 traffic through the Windows firewall. I'm not super familiar with Windows Server 2008 and I'm convinced that it's the Windows firewall or something in the OS that is causing the issue. Can someone help?

Server Config:
port 1194
proto udp
dev tun
dev-node MyTap
ca ..\\easy-rsa\\keys\\ca.crt
cert ..\\easy-rsa\\keys\\mykey.crt
key ..\\easy-rsa\\keys\\mykey.key  # This file should be kept secret
dh ..\\easy-rsa\\keys\\dh1024.pem
server 10.8.0.0 255.255.255.0
;server 192.168.1.150 255.255.255.0
ifconfig-pool-persist ipp.txt
push "route 192.168.1.0 255.255.255.0"
;push "route 192.168.20.0 255.255.255.0"
push "dhcp-option DNS 192.168.1.99"
keepalive 10 120

Have you tried disabling the Windows Firewall and trying to connect? If it works then there is definitely something with the firewall.

Yes I did that and it didn't work. I noticed on the old XP box, Internet Connection Sharing is enabled on the LAN adapter. I've also read a few things from other posts about enabling ICS. I did that but when I did, my LAN users were unable to resolve DNS. This server that I am setting up for OpenVPN is also a domain controller running DHCP and DNS services. I'd much rather have OpenVPN on a separate box, but we are short on rack mounted servers at this time. Not really sure what to do at this point.
