We have a PC based router that handles a public IP subnet of 206.XXX.XXX.192/27 and we have CPE that gets assigned an IP of say 206.XXX.XXX.194/27 GW 206.XXX.XXX.193. If we have another client with say IP of 206.XXX.XXX.195/27 GW 206.XXX.XXX.193 they can't ping the 206.XXX.XXX.194/27 client. Why? There is a single default route in the gateway and the CPE DOES allow ICMP. Internet traffic flows to and from the CPE fine it's just a problem with pinging a public (routable) IP from within the same netmask.
Am I missing something??
