I have configured a cisco ASR1K for CGNAT and it only works for UDP traffic, is there any specific config that needs to be made to have TCP work for CGNAT ?
CGNAT#show run interface gigabitEthernet 0/1/0.220 Building configuration...
Current configuration : 122 bytes ! interface GigabitEthernet0/1/0.220 encapsulation dot1Q 220 ip address 172.16.20.254 255.255.255.0 ip nat inside end
CGNAT#show run interface gigabitEthernet 0/1/0.162 Building configuration...
Current configuration : 122 bytes ! interface GigabitEthernet0/1/0.162 encapsulation dot1Q 162 ip address 172.16.2.140 255.255.255.0 ip nat outside end
ip nat settings mode cgn no ip nat settings support mapping outside ip nat log translations flow-export v9 udp destination 172.16.20.142 59999 source GigabitEthernet0 ip nat translation timeout never ip nat translation tcp-timeout never ip nat pool CGNAT 172.16.2.140 172.16.2.140 netmask 255.255.255.0 ip nat inside source list 2 pool CGNAT overload
