4.9 Trace
The NAT Filter keeps a list of the last trace entries in memory. You
may view this list by selecting the trace link. The handling of the page is
similar to the handling of the log page.
Each line contains an abstract of the received or sent packet. The
Time column shows you when the packet has been sent or received.
The Type shows if the packet has been sent or received; in
particular, „Tx“ means the packet has been sent normally from the NAT
Filter, “Tr” means the packet has been sent as message repetition, “Td”
means the packet was sent to a UA behind NAT, “Rx” means the packet
was received normally, “Rr” means the packet was received as a message
repetition.
