RV340 - Allow port forwarding only for certain source IP

[manuelmace84]

Hi to everyone.

I´m trying to configure port forwarding in a Cisco RV340 router but I need to enable that only for certain source IPs not for all the internet. In that router when you create a new port forwading, it automaticaly generate a new access rule in firewall configuration. This new rule is by default open to all trafic and it´s locked. I´m not able to edit that rule.
I tryed with port triggering function, but I couldn´t specify source/destination IP.
If I try with port forwarding, port triggering and personalized access rule in firewall (with one source IP) the port still opened for all the internet.

Someone can help me with this.

Best Regards.

high level you need to do Port-forward, the Add ACP rule to allow only required IP to access the resources.

Ok @balaji.bandi 

I think the solution it´s in the second link that you wrote: deny rule from WAN to VLAN was created also by default. I need an aditional deny rule for traffic from WAN to VLAN1. I will try with that.

Thank you.
