View NAT Translations?

Routers
1

Can any of you gurus tell me how I can view active NAT translations? I would like to see every open socket that an inside IP address has to what outside IP, what port and what protocol. For example, if I have some device 192.168.1.100 that is doing a DNS query using google, I want to see a listing of:
192.168.1.100 - 8.8.8.8:53 UDP
Is that possible? I’m from a Cisco background and the command in a Cisco router is just “show ip nat translation”. I’ve SSHed into my Route 10 and played around with arp, iptables and netstat but I haven’t had any luck. It looks like the ss command would be what I’m wanting, but it is not available on the Route 10. Are there any commands that I might be able to use to get some of the info?

Thanks

I think conntrack might do what you want. If you haven’t tried it out, give conntrack -L -j a shot from the shell. I belive that’s should list all NAT connections being tracked by the router.
