I have recently bought two CISCO routers RV220W for our main and brach office mainly for VPN tunneling. I didnt know they are routers only not modems. so I have set it up using BT 2wire Router as modem only.
I have successfuly setup the routers and manage to establish the VPN tunneling between two routers.
AS bt doesnt give static WAN IP address so I have used Dyndns which works fine. although I have 5 static ip address which cannot be used for WAN unless i cahnge to one IP address even then BT tech said it will not work.
when I created the tunnel i could ping both servers with their IP only not with the names. I can ping them fine locally. I could also see the network from branch office to main office but not from main office to branch office. today when I restarted the server I cannot ping both server i mean vice versa but VPN tunnel is established. now I cannot see the network from branch office to main office as well.
both sites running windows server 2008 standard. main office server has 6 NIC cards two wwith public and three with private ip addresses, its also runing Terminal server, exchange, file etc. the branch office has two NIC card one with private and one with public ip.
intially I could establish the VPN tunnel as the network range was same on both sites so I changed one in th e10.0.0.0 range other in 192.168.1.0 range and VPN tunnel was established straightaway.
As soon as the VPN tunnel was created I manage to creat an external trust without any problems and both servers are added in each other forward zones as name servers.
in the main office the fues went off and I had to re-start the router and now the VPN tunnel is not establishing, mainly the error is ISAKMP-SA Expired I will paste the log of both routers below
Now I need your help.
1. How to Clear Old or Existing Security Associations (Tunnels) on RV220W
2. how to fix the problem where I can ping the server with their IP as well as domain names ?
3. how to set it up so that both sides can see the network resources as well as access it ?
4. how to set it up so if the staff in branch office wants to log on the domain in main office he can simply do it as he does it in his office.
I can remote desktop both servers without any problems.
I have rebooted both servers few times, I have changed the share key, I also deleted the old setup and created new on both server but still no luck
Any urgent help will be appricated
