Connectivity issues after applying new configuration
I have installed pfsense in a Lenovo TS140 with a Xeon E3-1225v3, 32Gb ECC, 1x Intel i350-T4V2 and 1x Chelsio T520-CR.
I'm trying to troubleshoot the loss of connectivity that always occurs after applying a new configuration (e.g. create a new vlan).
Currently both WAN and LAN interfaces are in the Intel i350 card.
I though it would be something wrong with the network card but after swapping it with another one (same module) same thing happens. Removing the Chelsio card also doesn't solve the issue.
Is there any known compatibility issue with that NIC? Where should i look in order to better understand what is the problem?
What exactly happens? What connectivity is lost?
This happens with any config change? Creating a new interface is quite a big config change compared to, say, creating an alias.
Nothing in that setup should present an issue, they are all well tested components.
When you hit this what do you do to regain connectivity?
