Port forwarding on FVS318G

it was 5000 range ports.

forgot, should not matter. isp is dsl? PPPoA?

adsl, pppoe

if it is PPPoE then you should able to get bridge mode

have not clue to your ISP but you want PPPoE authentication at FVS will be nice

There are few setting were you can authenticate at DSL and pass through traffic. I think NAT is enabled on DSL unit that is causing since passing FVS works.

you issues is more on ISP provided device settings then FVS

This evening i check if is real pppoe because i not insert any user or pass on the isp modem/router.
The nat is enabled on dsl unit (static nat to 192.168.1.2)
There'isnt a way to use port forwarding with double nat?

Not in double NAT

Contact ISP for best solution !:)

I solved with upnp on FVS, the server has configured the ports on the router and now work.

Thanks

upnp are mostly for outbound needs but if you disable upnp and works then that is great.

sometime it can create an issues

Thanks jmizoguchi but upnp are my only WAS, the isp can't do e wouldn't do anything for help me.
If are disable upnp the ports remain closed.
A this moment are my only solution.

Thanks
