I have a router cisco 836 with this features:
CPU rev number 7
1 Ethernet interface
1 ISDN Basic Rate interface
1 ATM interface
128K bytes of NVRAM.
12288K bytes of processor board System flash (Read/Write)
2048K bytes of processor board Web flash (Read/Write)
The question is, when I apply this configuration, the router do not assume the static nat.
access-list 100 deny ip host 126.96.36.199 172.22.12.0 0.0.0.255
access-list 100 permit ip 188.8.131.52 0.0.0.255 any
route-map nonat permit 10
match ip address 100
ip nat inside source static tcp 184.108.40.206 3389 213.XX.XX.XX 3389 route-map nonat
Everything seems fine but if I do show running-config, it apears:
ip nat inside source static tcp 220.127.116.11 213.XX.XX.XX route-map nonat
If the router reload, the router do not assume the nat to port 3389. It just make a static nat between public and private IP so we lost the connection to router and the customer lose the communications.
