firewall on Cisco RV042

[sfx2000]

You may have to rethink your rules. It is all a learning process. Maybe they need outside access.

I would agree...

Short course on LAN firewalls...

Deny Incoming
Allow Outgoing​

This basically is similar to NAT - with an SPI firewall, we can then start opening ports

Allow TCP/22​

This opens the SSH port on the firewall for incoming traffic

Allow UDP/1194​

This opens up the port for incoming OpenVPN (per defaults - OpenVPN has numerous options here, some better than others)

From what I remember on my rv's (been a while since I've used them), you can enable intervlan routing with a checkbox, but it was an all or nothing option. And it was a port based vlan from what I remember.

The Cisco RV routers span many years. I believe in the very old days VLans were port based. The RV320 which has been around 4 or 5 years that I have allows Vlans tagged and untagged between 2 and 4096. The RV320 only has 4 ports so you are limited unless you connect a switch.

I have not used the new RV340 router which may have more features.

I think you have always been able to use ACLs on both the WAN side and LAN side.

Good to know they've moved to tagged vlans. The rv-series has always had a lot of bang for the buck.
