Destination Nat from Cisco Is 1900 router to firewall

Hi all,

 

we have configured dynamic vpn in a firewall which is behind a Cisco firewall. 

 

But remote clients are unable to connect to vpn configured in the firewall which is
behind the router where isp link terminates.

 

Any help on how we can configure a path from isp interface in the router pointing to firewall interface? Can Destination/source nat work here? If so how can we configure it

.

 

Thanks.

Can you able to provider Cisco 1900 router configuration to review.

 

Make sure you have right NAT in place for port 500/4500

Hi,

Use the below configuration but for more information, we required your network details as a network diagram, etc.

  • ip nat inside source static udp inside_ip 4500 interface interface 4500

  • ip nat inside source static udp inside_ip 500 interface interface 500

Inside_ip = IP address of the firewall

interface= WAN interface of the router.
