Can someone tell me how applying "ip nat outside" to int f0/1 causes the VPN to fail? The VPN is from 192.168.103.0 network on a remote site to the 10.5.1.0 network on int f0/0. Should I be using IP NAT Service? config is attached

Hi,
The reason is this: you redirect the ISAKMP port (UDP 500)
ip nat inside source static udp 172.16.3.200 500 wan.wan.wan.248 500 extendable
Change the port on the NAT statement and keep UDP 500 clear for VPN.
Please rate if this helped.
Regards,
Daniel
