pfSense to still route local LAN traffic when Internet/WAN Gateway is down

ghelfrich919

Here is my question. Can I configure pfSense to still route local LAN traffic when the internet/WAN gateway is down?

For example, my AT&T internet was down last evening. And when my internet is down, I am unable to access my local network. It was only when my internet came back did I have the ability to access local LAN resurces again.

I'd like to think pfSense can be configured to still route this local traffic when my internet is unavailable.

Any help is greatly appreciated.

That is the default config.

@Bob-Dig That's what I would have thought. Unfortunately, that's not the behavior I am seeing. Any idea what's going on here?

@ghelfrich919 You're going to have to tell us more about your setup so we can help explain what's happening.

Do you have an always-on VPN configured?

Here is my simple configuration:

192.168.102.0/24            
 |---------|           |----------|      192.168.102.65 |---------| 192.168.1.x   192.168.1.y   |----|
 | Clients |<--------->| Switch 1 |<------------------->| pfSense |<--------------------------->| GW |
 |         |           |----------|                     |---------|                             |----|
  ---------                  |
                             |
                             |
192.168.102.0/24             |
 |---------|           |----------| 
 | Clients |<--------->| Switch 2 |
 |         |           |----------|  
 |---------|

And no, I don't have always-on vpn configured.

@ghelfrich919 There is no routing in that setup.. You have 1 network shown 192.168.102.0/24 - pfsense has ZERO to do with devices in that network talking to each other.,.

Maybe dns was down? but in that setup as drawn pfsense could be off and 192.168.102.x could talk to 192.168.102.y

Unless your drawing is suppose to show some other downstream network via that 192.168.1 network? But the way you have that drawn would assume that is your internet. You list it having a gateway..

Where is the internet in that drawing - did you just leave it off? But if the internet is some other interface on pfsense - and it was down pfsense would still route its other local networks.

When your internet goes down, can you ping 192.168.102.65 from something else in the 192.168.102 network?
