Hello,
I am not a networking guy but pick up things fairly quick and need some of your expertise and guidance to help me make the most of the my RB951G-2HnD router. ![]()
I am a home user only and am able to connect to my company via their VPN client, however I noticed today that I do not appear to have their suggested configuration set-up in my firewall even though it is working - will this matter? and if yes, what should I add to my existing configuration?
From the Company info:
Firewall configuration for remote access
The following ports must be open on your ISP, router and firewall to create a successful VPN connection.
Packet filters for Point-to-Point Tunneling Protocol (PPTP)
TCP destination port of 1723 = PPTP tunnel maintenance traffic
IP Protocol ID of 47 = PPTP tunneled data
Packet filters for Layer Two Tunneling Protocol over Internet Protocol security (L2TP/IPSec)
UDP destination port of 500 = Internet Key Exchange (IKE) traffic
UDP destination port of 1701 = allows L2TP traffic
UDP destination port of 4500 = IPSec network address translator traversal (NAT-T) traffic
