Hi

I am facing problems while adding new network card.

Current Config of ethernet ports

1 x Onboard  - Lan
1 x Dual port Ethernet card - WAN and OPT1
1 x Ethernet Card - OPT2

I am adding

1 x Dual port Ethernet Card - I am trying to add OPT 3 and OPT4

But after adding the latest card I cannot access the pfsense from internal network, if i remove the new card then everything becomes normal again.

Please help what am I missing.
