In your dst-nat rule, you need to change in-interface to pppoe-out1 ... current setting to "bridge" is wrong, packets targeted at public address don't pass bridge until dst-nat is already done.

Hello thank you for your help. I have changed the interface to pppo-out1 and try it again I can access the router be the IP address then try IP address:3999 nothing ?

Normal dst-nat rule as set now works if you try from outside (e.g. from public internet host). If you want to have it working from inside (e.g. your LAN) as well, you have to implement so called hair-pin NAT. Search around this forum, it has been discussed several times.

Hello there I'm working out on the public ip not in the lan

You also need to change all in-interface= from “BT Modem” to ppoe-out1 in your ip/firewall/filter. And then either add ppoe-out1 to the interface-list=WAN or change your ip/firewall/nat masquerade to out-interface=ppoe-out1 instead of using the list.

Hello there is there any way to private message you ? I have tri that still not working think of send you my ip and login info see if you can see what up with it
