Hi

I have configured a VPN through ISA server and we have a DSL connection.

Now I want to add a Port forwarding option in our router for accessing VPN users from outside of our network.

What Public Port and Private Port and Port type I have to add in router for VPN connections.

If somebody can help me on this issue, it would be highly appreciated

regards

Jinesh

Usually if your just port forwarding you need to forward these ports

TCP 500 (ISAKMP)
TCP 50 for ESP
TCP 51 for AH authentication header

although you might need port 1723 open if the VPN  is using PPTP

Hi PeteLong
Thanks for your updates.

I will do the same and we are using ISA and using PPTP.

Also, can you please explain once I did the port forwarding in router, when I create VPN client dial-up account, which IP i have to put ! router IP or ISA IP, or I have to create dns names using for ex. dyndns.com. please advise this also

regards

(Assuming ISA is behind the Router) then use the router address :)

As the impact and severity of crypto ransomware attacks has grown, Webroot fought back, not just by building a next-gen endpoint solution capable of preventing ransomware attacks but also by being a thought leader.

It would be worth checking to see if the router supports VPN pass through.  You then simply need to enable that.

You need a Public IP address from your ISP Im afraid - Ask if they can reserve you an IP
