Linux systems unable to reach out to internet behind pfsense while Windows work fine.
I am trying to set up my #homelab for #forensics and I have encountered a very weird issue. I am running an internal pfsense #firewall for my environment. On this firewall there are 3 interfaces: WAN and two Isolated Labs.
On the “WAN” interface, both #linux and windows systems are able to access the internet without any problems.
But on the other two lans - named Infrastructure and Lab - the Linux systems are not able to connect to the internet after booting, while the systems are able to communicate with each other. In order to get them working I need to go the respective interface and make any change there and save the page, practically refreshing the settings on the interface. After this all currently online linux systems on that interface are working as expected and connectivity is restored. As you can imagine this is a huge pain, especially when I am testing things and I need to turn on various systems at different times. If i put the systems on the WAN interface they face no issue at all, so what could be the solution here for fixing connectivity for linux systems on the other interfaces?
edit: it issue is both on pfsense 2.7.2 and 2.8.0

The way your describing this isn’t quite clear. I think you have something crossed. There are a series of videos by Lawrence Systems on YouTube where he walks through basic to complicated PFsense configurations. I think it’s worth watching. What your trying to do is setup two vlans I think? They probably don’t have access to the WAN which you need to allow as this is not the default.
It seems complicated but making firewall rules makes sense once you get the hang of it. The best part of home labbing is learning though it usually requires breaking some stuff in the meantime. All part of the journey. You’ll get there, have fun.
