VPN Setup

Depends on how the VPN is configured.  Could be TCP or UDP, and then the port numbers it is negotiating accross.  give us some info on the VPN.  Also What Protocols is the VPN using?

I'm using PPTP and L2TP.

Some excerpts I have found:

PPTP uses port 1723 to establish and then uses the GRE 47 for the tunnel.

"PPTP can be used with most firewalls and routers by enabling traffic destined for port 1723 to be routed through the firewall or router."

L2TP encapsulates original packets inside a PPP frame (performing compression when possible) and inside a User Datagram Protocol (UDP)-type packet assigned to port 1701.

Much thanks. I will opened the suggested ports on my router and see if it resolved the issue. I will let you know.

If that doesn't work you will want to check with your ISP (unless you are leasing a line, then it "should" be wide open) to see what ports if any they block/deny

G'day,

Keep in mind that for VPN passthrough is not only ports on the TCP 1723 but your router must support Generic Route Encapsulation (GRE) protocol forwarding. With out it you VPN tunnel will not work.

Hope this helps,

I guess I didn't state that more clear above but Arthur Mino is correct.

G'day tlbrittain,

Thank you for your feed back.

Cheers,

Hey guys - I really appreciate your comments/suggestions. One question...does a linksys router - WRT300N support all these tunnels/ports (1723, 1701, 47)? Especially GRE?

Thanks for all of your assistance.
