Hello
This is my scenario:
Internet - router Cisco 836-- FW appli.
I've configured NAT in my router
Ports UDP 500,4500,2746
Ports TCP 256,264,1723
Portocol 50
It seems that works but in my router log I see some messages about ESP NAT translations.
*Mar 4 02:52:29.641: NAT: IPSec: inside host (172.0.0.16) is trying to open an ESP conn to 83.131.93.2, cannot process request from 172.0.0.16
*Mar 4 02:52:59.633: NAT: IPsec: using mapping to create outbound ESP IL=172.0.0.16, SPI=A395EEB3, IG=113.96.3.**
*Mar 4 02:52:59.637: NAT: IPSec: inside host (172.0.0.16) is trying to open an ESP conn to 83.***.66.2, cannot process request from 172.0.0.16
Are there messages right in an IPSEC NAT Process
thanks

After the connection and authentication completes, the client does not receive any traffic for over a minute while NAT cycles thru these messages:

just wondering if you are doing port forward or 1-1 ip nat. with ip 50 (i.e esp), you'll need a 1-1 ip nat.

Hello Guys,
I'm facing the same problem on a 2811 router.
Did anyone find a solution for it?
