Connected but can't ping

[BiosFlasher]

My setup is:

vpn client >> firewall >> internet >> router >> vpn server

-The router has port 809 (udp and tcp) forwarded.
-I have no control over the firewall which blocks all incomming udp traffic.

I can connect to the vpn and see published routes in GateKeeper, but can't ping the server from the client or the client from the server.

The routing table doesn't change after connecting even though i have "Send local RIP2 updates" and "Enable RIP2 listener" enabled on both server and client.

Hi there

WinGate VPN uses UDP to transfer data so this is vital to the VPN operation. If you have no control over the firewall that is blocking UDP protocol then the WinGate VPN wont be able to fiunction correctly.

Is there no possibility that the UDP port 809 on the firewall can be set to redirect traffic directly to the client machine behind?

Thanks for the quick reply.

It seems like everything incoming is blocked. Does the client also need to have port 809 tcp forwarded to it?

Is there any hope for the client to be able to join any vpn solution (maybe based on tcp)?

A strange thing is that the client can send and receive files on msn. Im not sure how msn file transfer works, but doesnt that mean some ports are open? I tried changing ports in Gatekeeper to 6901 and some other msn ports, but nothing.

No, the client doesn't need TCP forwarded as that connection is established from the client already. The client has effectively punched an outgoing hole in the firewall.

However, if your firewall is blocking all UDP traffic you won't be able to use WinGate VPN. As Erwin said, it requires UDP for the data channel, which is in effect all the network data.

It uses a private protocol which will not talk to other VPN solutions. Do you have physical access to the firewall? To the point that you can check in logs to see if it blocks all UDP / the data coming from the remote VPN client?

No the firewall is operated by my university.

Anyway I got OpenVPN working when i changed the default from udp to tcp.
