I have an RV180 as gateway and router for four VLANs, including adm VLAN.
The setup is:
VLAN1 - 192.168.1.0/24 - admin
VLAN10 - 192.168.2.0/24 - wired
VLAN30 - 10.1.1.0/24 - WLAN
VLAN31 - 10.1.2.0/24 - guest WLAN
The RV180 has an external IP and all traffic out is NATed through the external interface. So far so good.
What I don't understand is why all traffic between VLANs also seems to bet NATed. If I connect to a host in the wired VLAN10 from a WLAN client on VLAN30 the traffic gets NATed with the RV180s IP address in the wired subnet. Is there any way to avoid this?
The RV180 is configured in NAT routing mode. Will putting it in router mode and having explicit access rules with NAT for outgoing traffic fix my issue?
