Cannot ping OPT1 interface between two pfSense boxes.
Here's my setup, which I intend to install CARP on when I have them communicating correctly.
Two Dell PowerEdge 1850 machines with one of the Broadcom NICs turned off (I was plagued with Network Interface Mismatch errors when both were turned on. I think there is something buggy here as I've never seen a response in the forums that overcomes this issue reliably when using multiple NICs from the same manufacturer). In each machine I have added an Intel NIC & a 3COM NIC.
em0 (onboard Broadcom) is assigned to the LAN with 192.168.90.2/24 in the first box & 192.168.90.3/24 in the second (these will be virtualized to 192.168.90.1 later for CARP)
fxp0 (Intel) is assigned to the WAN with Static addresses at 192.168.17.2/24 and 192.168.17.3/24 respectively (again later to be virtualized for CARP)
el0 (3com) is assigned to the OPT1 interface, which I have renamed to SYNC on each box. One box has the address 192.168.0.2/24 & the other 192.168.0.3/24. Both interfaces are enabled.
On each box I have created a Firewall rule for the SYNC interface that passes all traffic any protocol everywhere i.e. all * in the Proto, Source, Port, Destination, Port, Gateway boxes. I then hooked the two SYNC interfaces together by a crossover cable. Status/Interfaces shows both SYNC interfaces are UP. Diagnostics/Routes shows what I think is correct, i.e.:
192.168.0.0/24 link#1 UC 0 0 1500 xl0
So I thought that with the firewall rules created, the route table looking fine & the interfaces connected by a crossover cable I should be able to ping the other machines SYNC interface from Diagnostics/Ping, but no dice, I get:
Ping 192.168.0.2 (192.168.0.2) from 192.168.0.3 :56 data bytes
–- 192.168.0.2 ping statistics ---
3 packets transmitted, 0 packets received, 100% packet loss.
I know I must have missed something, but no matter how many time I go over it I cannot see my mistake, which there must be.
Can anyone help me see the error of my ways?
Please ignore my ramblings. It was a state issue.
