Question Transparent Bridge and Firewall
-
Hello,
I need to setup a transparent bridge. I found this in the forum http://forum.pfsense.org/index.php?topic=50711.0
Great read very easy to follow.Here is my situation-
I have 100 meg fiber line with a Ethernet hand off. Currently my provider installed a Cisco ME3400 for the hand off. I was assigned a block of IP's
77.x.x.x/30 but actually needed a class c.So I went ahead and ordered a class c. Now I have 2 separate IP blocks.
WAN -> 77.x.x.x/30
LAN -> 66.x.x.x/24I have to use the 77.x.x.x for the hand off to them. Is it possible to bridge the 2 different blocks together?
Example -
WAN <–> 77.x.x.x <--> 66.x.x.xI hope that makes sense.
Thanks.

You could have you ISP route the 66 network to one of your 77 addresses. This would be an ideal routed solution. You will need to disable nat. I would not bridge if I where you.

They told me that they assigned the 66 block to the same vlan as the 77 block.
So if I just do a standard router setup.
Wan - Static ip 77.x.x.x
Lan - 66.x.x.x block using DHCP / and no NatThis should be ok?
Really appreciate the help.
Thanks,

No. That I'd not sufficient. The ISP must route the 66 block to a 77 address. Otherwise you are going to have to bridge or perhaps proxy arp.
