igb3 dropping packets from igb1

[tinz]

igb1 = 10.10.10.0/24
igb2 = 10.10.20.0/24
igb3 = 10.10.30.0/24
igb4 = 10.10.40.0/24

Each interface has the 'allow all' default rule
interface: <whichever>
Portocol: ANY
Source: <interface NET>
Destination: ANY

From igb1, igb2 and igb3 I can ping/connect to any device on the other subnets, but none can connect to igb3, and no devices on igb3 can connect to any of the other sybnets.

Devices on all the subnets can connect to WAN and WAN can reoute to all subnets.

The states view lists any attempted connections to igb3 with SYN_SENT:CLOSED

I've been googling and trying so many things but I can't get that wall to open.

HELP!

@tinz Some devices will not respond to traffic form a different VLAN. Not sure if this is the case. To get those devices to respond you would need an Outbound-NAT rule to make it appear to that device it is talking to the igb3_address.

Outboud NAT Rule:

Interface: igb3
Address Family: IPv4
Protocol: Any
Source: Network igbx_group (or igb1 and repeat for others)
Destination: Network igb3
Address: Interface Address
Outboud-NAT to igb3 network
