Im having issues opening ports. I know this has been mentioned before however I've gone through all the settings, but all ports seem to remain 'filtered' or 'blocked'.   Ive setup port forwarding on the router, ensured firewalls are clear in my OS, but ports still not accessable.   Details: Modem: Hardware Version:Archer VR1600v v1 00000000 Firmware Version:0.1.0 0.9.1 v5006.0 Build 200810 Rel.53181n   Setup via NAT forwarding > Virtual Servers >  - internal IP set for static local IP address of a server I am running - Port set as needed - Protocol is both UDP/TCP   connecting to the server via LAN works fine, However when trying to access it externally it fails. I have the same issue for connecting via SSH, where I can only do so via internal IP address.   Perhaps I am missing something, or perhaps the ports are blocked at the ISP level, any help would be much appreciated.   Thanks.     ...
