We are looking to install an ADSL connection into a remote LAN. The LAN will contain 2 PC's and Ethernet based PLC equipment. The purpose of the ADSL is to allow 3rd party to connect to the PC using RDP for remote support.
What I would like is an ADSL Router\Firewall which can do the following:
*Restrict ports i.e. no http port 80
*NAT External IP's to local LAN IP (I'm hoping to have a couple of external IPS)
*Restrict the RDP traffic to only come from allowed IP's
Pretty basic stuff but I just want recommendations. Netgear\3com etc.
