FreeNAS box doesn't forward packages from networks it's not connected to

[Victor Tanvui]

I've got the following setup

192.168.1.0/24 10.15.0.0/24
(native vlan) (vlan 3)​

Internet ------------- Router -----------FreeNAS box ----------network

|
|​

OpenVPN jail
on FreeNAS BOX
bridged to native vlan interface

|
| (10.16.0.0/24)
|​

OpenVPN client​

As far as I can tell routes are setup OK (static routing). The problem is that I can't ping end to end (from the VPN client to the 10.15.0.0/24 network). Ping between the OpenVPN client and the FreeNAS box works and also pings from the 192.168.1.0/24 network to the 10.15.0.0/24 network work as well.

Any ideas why the FreeNAS box won't forward packets that come from the 10.16.0.0/24 network?

On Linux I know there's something called Reverse Path Filtering which has caused me some problems of the kind in the past, but I can't find anything like it on FreeBSD.

Thanks in advance.

Did you figure this out?

Hi,

Sadly enough no. I haven't been able to pinpoint the issue. We've ended up modifying the topology and using a linux based router.
