I am having real problems getting some users onto our VPN. UDP 500, UDP 4500 and ESP are all being allowed through our firewall and we have existing users coming through fine and authenticating to the VPN Conc. However, some users, with the same client profile etc are being prevented. I got some logs last week which showed the following (non-Cisco firewall)
with the 81.x.x.x being the source IP and 10.200.x.x being destination. What I don't understand is why UDP 5454 is showing when other users - that connect fine show this (UDP 4500 etc)see below
Is the destination address (10.200.x.x) blocking the packets for the users that are having problems?
Any help much appreciated.
