Unable to connect to VPN through NetGear FVX538 VPN ProSafe Firewall.
Posted on 2006-06-20
I have had so much trouble using the Netgear VPN firewall and the VPN client software that I have decided to abandon this setup and venture into something new.
I'm now trying to set up a VPN with the provided, free software that comes with Windows XP Pro and Windows Server 2003. I have successfully setup the VPN servers-side with Tech Republic's help and white papers and I have also setup the client-side of the VPN as well.
Now I'm at the part where I'm using pptpsvr.exe and pptpclnt.exe (free from Microsoft) to test whether or not the request from the client is making it through the NetGear firewall and making it to the VPN server. Then the VPN server should reply back to the client with "x" number of GRE packets.
This is my problem. I can't get a reply from the VPN server so I assume that the request is not making it past the firewall. I have opened up port 1723 and forwarded it directly the static IP of the VPN server. My client is on another network with an IP of 192.168.0.x while the network I'm trying to connect to is on network 192.168.1.x. I did read that I have to set up IP protocol 47 as well. To my knowledge this IP protocol 47 is not TCP/UDP port 47. I don't know how to configure this IP protocol 47 on my FVX538 VPN ProSafe firewall in order to allow my VPN request to reach the server. Any ideas out there on how to configure this IP protocol 47?
I need this issue to be resolved asap in order to keep my boss happy!
