Hi!
I've got random connection issue when I try to connect to a VPN gateway through an ASA 5510 (IPSEC client ->ASA 5510->VPN Gateway).
When the tunnel is coming up, those two lines appears in the captured traffic on the internal interface :
<private internal IP>.500 > <destination IP>.500: udp 541
<public external IP>.500 > <destination IP>.500: udp 541
When it's not coming up, the port nuimber for the public IP is not 500
(private internal IP).500 > (destination IP).500: udp 541
(public external IP).442 > (destination IP).500: udp 541
I don't understand why sometimes the port for the public external IP is 500 and sometimes not. Any explanation ?
Thanks for your help.
Chris
