@W4RN3R See, To host this SA-MP Server. I would recommend you for using Playit.gg in place of Port Forwarding. From my self experience I'm saying as I've hosted many Different Game servers using Playit.gg without getting anywhere stuck with Port Forwarding or this type of things.
Using Playit.gg is much more reliable than doing Port Forward for hosting a Dedicated server (specially for Games) as you get 1 privacy wall by Playit.gg and get 1 IP Address which will not change if you don't want to get Static IP address
