LAN not getting routed through default GW
I've been racking my head against this all day and can't seem to get anywhere. I think I've covered all the basics but haven't gotten anywhere.
I can't seem to access the internet from the LAN. Trying to ping an IP or a name both fail.
My WAN has a static IP and according to the Routing table in pfSense, the default GW is the proper GW for my WAN IP.
From the pfSense box I can access the internet fine, one curious thing though…from pfSense, if I try to ping 18.104.22.168 using the LAN interface I get nothing. I test this with another pfSense box I have and I could do it so I think that's supposed to work.
The gateway on my laptop is set to the pfSense IP, so I know it should be getting that far anyway but seems to stop there.
Thanks for any insight into this, I know it's a somewhat common question and generally is a simple solution.
Ok, I don't know what it is but it seemed to be a bug. I ran the General Setup wizard again per somebody's suggestion, didn't change anything and now it's working. Seems changing some things manually doesn't take full effect somewhere. I did originally have a different LAN subnet set and changed it later manually. All is well now.
Sounds like maybe you didn't have the gateway selected on Interfaces > WAN which made automatic outbound NAT fail (similarly, adding a gateway on the LAN interface will break it)
This sounds like my issue. Are you saying that we can't use a gateway on LAN at all? What do you do when pfSense is sitting in between a router and the WAN? If I don't have a gateway set on LAN then pfSense can't find nodes on LAN subnets routed by our L3 switches. But if I set the gateway on LAN all routing breaks. So what can I do besides stick to 2.0.3? (on which it works)
You can define a gateway for LAN on System > Routing for static routes
You should not select a gateway on Interfaces > LAN
Is it really that simple? I'm going to try this tonight when I can create some downtime. Thanks!
