I am using ASL6 and with http proxy enable for my user and some of my user need to vpn using L2TP IPSec, What port do i need to open on Packet Filter? Pls help
No need to open a packet filter on ASG itself, because this is done automatically. If you like to open a packetfilter on another machine in between the connection you have to open port 500/udp, 4500/udp (if using NAT-T) and the whole protocol ESP(50) (if not using NAT-T).
