inbound NAT rule with port openings on router needed

[atrevido43]

Not sure where to start, I have 5 static IPs available on my inbound T1's, one is in use for the outbound nat overload pool.   This site now is getting some ADT security cameras.  They want some ports opened and a public and private address.  Ports 8200, 8016, 10019, 8201  This is an 1841 router with ACL's applied on all the interfaces.  How do I program this inbound NATing to go to the private IP with certain open ports?

Hi,

Your nat would look like:

ip nat inside source static tcp 8200 8200 extend

ip nat inside source static udp 8200 8200 extend

Only open what you need to the outside (in other words if you only need udp, then don't map tcp). On an acl on the outside, you'll want to allow the traffic inbound.

HTH,
John

This is what I ended up using

ip nat inside source static tcp 10.x.61.245 80 12.1.1.6 9001 extendable

ip nat inside source static tcp 10.x.61.246 80 12.1.1.7 9001 extendable

Many thanks for your help
