I'm sure this was working before (on other client sites), but I cannot
get this going again.
All I want to do is add a subnet (/29) to the WAN port so I can use
all the addresses that my ISP gives me.
I have allowed ICMP traffic to all these addresses with a rule.
ICMP * * x.x.193.200/29 *
And I have added a server NAT entry
External IP address Description
In my fw log I see
OK 18:36:47.202983 WAN 126.96.36.199 x.x.193.203, type echo/0 ICMP
and it has a green arrow showing the traffic was allowed.
Yet the site I ping from says:
PING x.x.193.203 (188.8.131.52) 56(84) bytes of data.
From x.x.193.202: icmp_seq=3 Destination Host Unreachable
From x.x.193.202 icmp_seq=3 Destination Host Unreachable
From x.x.193.202 icmp_seq=4 Destination Host Unreachable
--- 184.108.40.206 ping statistics ---
4 packets transmitted, 0 received, +3 errors, 100% packet loss, time 2998ms
The address that replies with the "destination host Unreachable" is
the WAN port IP.
Why is this happening? It worked perfectly before at other sites, but
I can't find the error here.
This should not be difficult, or should it?
