Static NAT Translation

[sreeraj.murali]

Hi,

I want to allow access for one of my Internet LAN IP, 172.20.4.44 to be accessed from outside. I have configured the Inside Static NAT Translation. Please find the below output from the

show ip nat translation.

Pro Inside global      Inside local       Outside local      Outside global
gre 49.204.83.10:0     172.20.4.44:0      74.116.72.7:0      74.116.72.7:0

Please help with the correct configuration required for permitting this access.

Thanks & Regards

Hi Sreeraj,

Looks like you have already configured NAT. But while accessing a LAN ip on a specific port from outside you must have a static NAT entry available which can be used during reverse NAT translation when traffic hits from outside.

try:

ip nat inside source static tcp/udp 172.20.4.44 <tcp/udp port>49.204.83.10 <tcp/udp port>

please rate if it helps
