I have enabled WAN2, with static IP 82.35.13.250 with a mask of 255.255.255.248 and gateway of 82.35.13.249

I have added a WAN IP alias of 82.35.13.252

I have gone to NAT DMZ and links 82.35.13.252 to 192.168.1.10

I have a PC with firewall off at 192.168.1.10

And a PC at 82.35.13.253 (mask 255.255.255.248)

....but using the PC at 82.35.13.253 I cannot get ping response from 82.35.13.252 (although 192,168.1.10 will return pings through LAN port on router)
