Port_Forwarding

Arif — Fri, 21 Feb 2020 16:54:33 GMT

Hi;

I have Cisco 5516-x Firewall. I want to permit access to specific devices from outside via specific ports. Where and how can I set requiring settings on this firewall. Thanks...

It would via via an access-list on the outside interface.

If you have NAT, you would specify the destination host's real IP address, not the public NAT address.

Hello, you can do it though NAT configuration, like exemple below:

ip nat inside source static x.x.x.x (ip public) xx (port) x.x.x.x (local ip) xx (port)

Hi;

Can I achive this from gui (I don't know cisco commands too much). Can I use NAT tab on firewall (see attachment please). I think I should set "original source" : any and "translated source" : My DVR's local IP. am I think true ? Thanks...

original source: public ip address / interface and port

translated address: local ip of your dvr and port

Hi;

I can't select "public ip address" as "any" from Auto NAT rule, Only from Manual NAT rule I can select public ip as "any". In that case what should "original destination" is (can't select any from here). Thanks...
