WR21 is blocking 500 port. How do I connect my external vpn router via the WR21 ?
Port forward 500 port ?
or
DMZ, where is in the menu ?
Hi
if you are doing port forwarding you are going to have to use the firewall as you dont just need port 500 you also will need protocol 50 for the esp packets
yjr fire wall rule for port forwarding would be like this
pass in break end on ppp 1 proto udp from a.a.a.a to any port=ike -> to z.z.z.z
pass in break end on ppp 1 proto udp from a.a.a.a to any port=ikefloat -> to z.z.z.z
pass in break end on ppp 1 proto 50 from a.a.a.a to any -> to z.z.z.z
pass out break end on ppp 1
information on the firewall can be found here
