IN DSL, you may need to check out how to port forward with a STATIC I.P on your Modem and/or router
In Wimax and LTE, you cannot do this as wireless connection of globe are under strict-NAT
remotely viewing our cctv is also my problem...even using the easiest does not open ports with the Prolink H5004NK.
has anybody been successful with pf for such case? so much time and effort put to waste over this, hope a solution is available.
