Thanks More about : port forwarding cisco 2811 corroded April 9, 2013 11:08:28 PM you need to know cli... you have 6 ports on the untrust, 1 each, set ip on wan as you have and... m 0 l bill001g April 10, 2013 6:59:34 AM Unfortunately you have a lots of learning to do, the way you ask the question leads me to believe you have not configured cisco nat before. So the answers you want For the simple ones a example statement is IP NAT INSIDE SOURCE STATIC 10.xx.xx.4 210.xx.xx.228 The other ones you can't do. You cannot map a outside address to multiple servers. Now you can map say port 25 to one server and port 80 to another. A example of tcp port forwarding for port 80 is. ip nat inside source static tcp 10.xx.xx.5 80 210.xx.xx.229 80 extendable m 0 l Related resources Port forwarding on a cisco 2801 router - Forum Help please! - Cisco Lynsys E2000 - Port Forwarding - Forum Adding port forwarding on Cisco ASA - Forum Port Forwarding through Cisco 2800 - Forum Cisco PIX 506 v. 5.1 and port forwarding - Forum Can't find your answer ?

Here's what i did, i mapped 1 to 1 on two public ip to private ip: 1. IP NAT INSIDE SOURCE STATIC 10.xx.xx.3 210.xx.xx.227 2. IP NAT INSIDE SOURCE STATIC 10.xx.xx.4 210.xx.xx.228 For the remaining 3 public ip which will be used by 6 private ip with different port: ex: 10.xx.xx.2 (svr3) & 10.xx.xx.225 (svr6) will used 210.xx.xx.226 10.xx.xx.5 (svr4) & 10.xx.xx.226 (svr7) will used 210.xx.xx.229 10.xx.xx.6 (svr5) & 10.xx.xx.227 (svr8) will used 210.xx.xx.230 what i did, i create 210.xx.xx.226, 210.xx.xx.229 & 210.xx.xx.230 on each different pool: 1. ip nat inside source list 101 pool Public_Pool-A overload access-list 101 permit ip host 10.xx.xx.2 any access-list 101 permit ip host 10.xx.xx.225 any 2. ip nat inside source list 102 pool Public_Pool-B overload access-list 102 permit ip host 10.xx.xx.5 any access-list 102 permit ip host 10.xx.xx.226 any 3. ip nat inside source list 103 pool Public_Pool-B overload access-list 103 permit ip host 10.xx.xx.6 any access-list 103 permit ip host 10.xx.xx.227 any 4. how to add rdp port to access-list from any ip outside access to inside ip 10.xx.xx.6 on port 6969? what i need is that, all private ip can go out to the internet. only some ports are open on lan which is accessible from internet. thanks m 0 l bill001g April 10, 2013 9:56:31 AM What you have will work you just need to add the port level nats for 10.xx.xx.6 If I read it right you want to map the outside address with the default RDP port of 3389 to the inside server on port 6969 ? ip nat inside source static tcp 10.xx.xx.6 6969 ??.??.??.?? 3389 extendable m 0 l Can't find your answer ?
