Hi,

Also didn't work, any other suggestions please?

I did as you said and even added a reverse rule on both interfaces, I still can't ping nor access from each others.

If "WNGR" is your WAN gateway group, your first rule will be trying to use that for traffic from LAN to "muffin net", which you don't want - change Gateway for that rule to "default". You'll need rules on the VLAN interfaces too.

Tried that, didnt work.

Can you let me know what are the exact rules needed on LAN & VLAN to have them both talking to each-others?

Thanks

Hello,

Here is my setup:

Proxmox with OpnSense with 3 NICS (bridged)
NIC1: WAN1
NIC2: LAN
NIC3: WAN2

I have OpnSense configured with the LAN interface (192.168.4.1)

I have Multi-WAN configured grouped in WAN_GRP and I have the firewall rules set any-any default gateway WAN_GRP & a DNS rule in firewall above the any-any to allow UDP/DNS requests

I have 2 VLANS (192.168.3.1 - named "muffin") & (192.168.2.1) VLAN 30 & VLAN 20 respectively on a managed Linksys switch.

I am able from management interface to talk with all VLANs

What I want to do is to have the VLANs talk with each others, i'm unable to achieve that.

VLAN 30 is able to ping the 192.168.4.1 gateway but not devices in it.

I dont have block private networks checked on any of the LAN/VLAN interfaces.

Attached are my rules, i'd appreciate any help please.

Having the same issue, once I set in firewall LAN rule the gateway as the group DNS stops working...

Any solutions?
