[Spce-user] Selective NAT pinging switch off possible?

Hi all,

Happy Easter!

How can I switch off NAT pinging to destinations that do not need it?

I see nat pinging to every address 192.168.x and 10.x.x.x and 172.16-31.x.x … is this hard-coded? Shouldn’t it be only done to addresses where the "contact" domain address is different from the "received" IP address the request comes from?

Kamailio has a function in the pinger module for this (where the flag to omit pinging is specified in location table) but it doesn’t seem to be there in SPCE.

We have 10.x.x.x addresses on our network to our ONT equipment which doesn’t require NAT (as it’s directly connected)… If we could switch off NAT pinging to these addresses that would probably save a lot of resources on the NAT pinger as per my calculation we wouldn’t be able to exceed 96k subscribers on an SPCE installation, regardless on how much power and speed we give the machine this runs on.

Are there other “hard” limits on an SPCE platform that would prevent subscriber growth, other than perhaps concurrent calls ?
