Hello,
how on a NAT firewall server using iptables or nftables, are the
external source ports choosen ? I would say range is 1024-65535 but if
for instance I use port 5060 for SIP this one can not be used as source
port. Is there a table of at time used ports ?
Also, SNOM phones are systematically using port 2048 as source port of
the WAN ip. Is there a mechanism to allow such behavior ?
If you know any good documentation about this (without reading source
code ;)) will also be accepted :)
Thanks for your great job
