How to log NAT state table?

[magura]

I want to record information on the NAT,to syslog server.
ex.
udp 74.86.2XX.4X:1513 <- 192.168.33.44:1513 MULTIPLE:MULTIPLE
udp 192.168.33.44:1513 -> 12.10.2XX.44:1513 -> 74.86.218.40:1513 MULTIPLE:MULTIPLE
udp 17.1XX.10.1:9900 <- 192.168.33.97:11749 NO_TRAFFIC:SINGLE
udp 192.168.33.97:11749 -> 12.10.2XX.44:11749 -> 172.168.10.1:9900 SINGLE:NO_TRAFFIC

But the firewall rule log only private IP and destination IP connection information.
No NAT conversion information.
I use 1:1 NAT for many class C
I need more detailed LOG, how to make.
