Hello,
- How can I experimentally measure how long a router’s Network Address Translation is kept “alive” within router’s memory before being discarded ?
If that matters, my question relates to both SIP and RTP traffic, mostly done with UDP.
Are there some boxes over the Internet that simply echo with a configurable delay, inbound udp traffic ?
-
Would you say that for most routers this NAT timeout equals 20s or so ?
-
Any pointer to learn more about this ?
Best regards
