Destination NAT with ICMP

does anyone know why there is a limitation that i cannot choose the echo-request service on the NAT rule , and also in a group in the NAT policy.

only "any" will apply NAT to echo-request packets

thanks

Re: Destination NAT with ICMP

That is partly correct. You can build a general NAT rule and limit it with the firewall rule.

For more infos to destination nat see article .

Re: Destination NAT with ICMP

The service column in the NAT rulebase can only take TCP/UDP services, of which ICMP is neither.

If you've properly restricted your access rulebase, this should not present a security issue.
