Greetings, hopefully someone out there can help me out.
After about 6 weeks of searching the net for "how-to" guides for VPN I finally succedded in getting it to work.
I have a dir-628 with firmware 1.24na. I have the following virtual server settings in the advanced settings tab:
FTP - PORT 21 (this is a preconfigured setting)
PPTP - PORT 1723, also a preconfigured setting
The following is what took so long to find.
GRE (I configured this one and just named it) - the field with tcp/udp/both/other select other and put 4 in the protocal field.
Up the the previous step I kept getting entries in the lot that GRE packets were being blocked.
For the great news, I can now connect with my vista laptop through vpn to my server, I can even connect with my droid x (only if I put it in wifi mode, 3g/4g don't seem to work)
For the bad news, I cannot browse the network when the VPN is up, however since I have network connections on my laptop I can browse those when they reconnect. I think lack of browsing is due to some other ports not being open or netbios/netbui. I am still looking into it.
Here is the part that really sucks, when I disconnect the VPN connection and try to reconnect it gets stuck at the verifying password stage. The router logs indicate that GRE is again being blocked. This continues until I reboot the router. Then things are good once again for one connection.
This same scenerio occured regardless if it was the vista laptop or the droid x that connected the first time. In fact the router is so hosed that the FTP connection which had worked great from either remote connection is hosed. I have to bring down the FPT SERVER and restart it.
Has anyone ever heard of this before? it certainly sounds like a firmware thing but I have not found any information or of others having the same problems.
Thanks for any help that anyone can give.
