I am in dire need of some assistance.
We had, until a week ago, a very stable VPN setup. Single Win 2k server at our main office, and one Win7 client.
The Server 192.168.0.1 (Active Domain) provides all services (dhcp, rras, file server, etc.)
Nothing fancy, just a simple vpn, 1 user access from remote location. (me - I work remotely). both routers had nat. I was able to access the shares on the server (not other computers at the office lan, but that wasn't necessary).
A week ago, the very old - actiontec GT701r modem/router at the office died. No problem - we ran out to purchase a new one - this time an actiontec GT784wn modem/router
Modem/Router installed fine - no issue. changed ip address of router from default to old gateway address 192.168.0.2 Internet access resumed, with all local computers able to get out to the internet and and LAN access working great. Nothing seemed askew.
Set the router up to pass through PPTP and L2TP/Ipsec. (at the time I couldn't remember how we had the vpn setup). Turned off DHCP in the modem/router because the Office network gets dhcp from the server.
Went home - tried the vpn. No connection. VPN server wouldn't answer. I could ping the office wan ip fine. Home LAN is on 192.168.1.X, with the router being 192.168.1.1
Turned off all firewalls - tried turning off eset. Still no connection. I did get intermittent VPN connectivity (about 1 in 5 tries), but once connected could not ping the server and the connection drops after a short while (30 second or so) (actual connection was verified at the vpn server) which tells me that it's not an authentication issue.
This really seems like a routing issue to me, but nothing should have changed. It is possible that there was a static route set up on the old office router that was lost, but I am not sure what it would have pointed to.
server ip 192.168.0.1 > gateway ip 192.168.0.2 >office wan
home wan > home gateway ip 192.168.1.1 > home LAN 192.168.1.x
When it does connect:
ip 192.168.0.97 (given from vpn server static pool)
subnet mask 255.255.255.255
gateway - blank
Any help would be greatly appreciated.
