Hi
I might say this is confuse.
"can someone help me to solve this problem please
I have a 2900 series rotator so I have voice traffic which comes from the public ip 197.231.xxx.xxx which must arrive at its destination on a local server 192.168.30.21 but the local server's firewalls block the traffic"
The server´s firewall is blocking the traffic intentionally or this is a misconfiguration? dont follow you here.
"I would like to block the 80 from the ip 197.231.xxx.xxx and send it back by the private ip 192.168.30.21:5060 but the nat that I am using is blocking my router"
Are you saying here that you dont want the server to be open to the internet on port 80?
Port 5060 is SIP port and if this is a VOIP server, that port need to ne open.
NAT have no hability to block. You need to be more clear on this point.
"here is the conig that I made if you can give me a correction please"
ip nat source static 197.231.xxx.xxx 255.255.255.252
ip nat inside source static 192.168.30.10 255.255.255.0
ip nat outside source static 197.231.xxx.xxx 255.255.255.252
Those NAT statement is wrong. The NAT should be like this
ip nat inside source static <first IP address> <second IP address> I never saw the usage of subnet mask on this command.
If what you are trying to achieve is PAT, you can do like this
ip nat outside source static tcp 197.231.xxx.xxx 5060 192.168.30.10 5060
