NAT Keep Alive Intvl: 15 (vs. 28)

I seem to recall having a problem with setting this number too low on my Sipura, which was unexpected.

Substitute VIA Addr: no
Send Resp To Src Port: no

If these are no, then should we presume the four immediately above it are set to yes? I had heard that the 'standard' approach is either to make these two settings 'yes' and the other previous four 'no', or vice versa, the previous four to 'yes' and these two to 'no', but never do either all six to 'yes' or all six to 'no'. However that's going on someone else's understanding, this is not my speciality, so I don't really know for sure.

It does sound like you have 'bad' firewall/NAT settings from your above explanation so that is why I ask about these settings.
