Port STATUS VPN

[BWayne2k]

I have a winnt 4 box setup for a vpn, on my router i have opened all the necessary ports to connect to the server 1723,upd ports i found from microsoft and i have upgraded the firmware for my router to enable ip 47 i think, the tunnel server option which i have pointing to the nt server. I check the status of the VPN connection with the nt soft. remote access admin, and it says initializing modem, the computer where im dialing from gives me a
'verifying user name and password' but times out after a while with error 721 remote computer did not respond, I can even ping the router from a remote computer giving me a reply but the vpn doesnt work, does anyone have any info on this? thanks in advance

HI.

You should be able to ping the NT box from the VPN client, not only the router.
Is your router doing NAT - I guess this is your problem.
You should have a registered ip address for the VPN server, or at least a static nat mapping.

hey,

i have had the 721 error for ever and think i have found the problem. There are a lot of firewalls/routers that do not properly pass the VPN traffic even if you have all the ports set up correctly. I couldn't even establish a VPN session out of my network because I was running a Linux firewall. I am running a Netgear FV318 firewall now also and it WILL properly pass the VPN traffic for Windows 2000, so I am sure it will for NT 4.0 also. I haven't yet tested the traffice incoming (i will soon), but I am sure it will work now.

Long story short, upgrade your router/firewall for the latest technology and it should work.

Good luck,
