Is your WAN port set with the WAN IP or behind NAT?

Set rule 1 with source IPv4 to any

Hi @itdsc

i think you should modify your policy like this


also check your nat roule; "Ip Originale" = any

Hello @itdsc,

For your NAT rule, please set Source IP to "any", and your security policy rule 2 is not needed.

Moreover, once the NAT rule is created, the external port should be open, we're not sure the online port scan works correctly on our device.

If it still no work, please capture the packets on both WAN and LAN interface, provide to me through PM for further checking, thank you.
