Hello everyone, I am having issue with opening port in cisco router 1841. I've done the following things.
- I tried port forwarding
- ip nat inside source static tcp 192.128.3.13 1337 <inside global ip> 1337
- ip nat inside source static tcp 192.128.3.13 1337 <inside global ip> 1337 extendable
When I entered show ip nat translations I can see that port is mapped:
Pro Inside global Inside local Outside local Outside global
tcp xxx.xxx.xxx.xxx:1337 192.128.3.13:1337 --- ---

Inside global and local ip are all correct. When I saw that the Port is mapped I checked whether the port 1337 is opened but it's closed. I use this website to check. Previously some ports were opened by someone and it works well. But I am not sure why mine is not working. Basically I am trying to communicate with server to get data. I am using windows server 2019 standard. I am new to this thing and I'm learning as I am doing this. Any help is very appreciated. Thanks.
