Title: [SOLVED] Transparent Filtering Bridge not working
Post by: tmp on February 08, 2018, 07:12:45 pm
Dear opnsense-community,

I'm new to opnsense and need some help in setting up opnsense as a transparent firewall bridge for content filtering. I'm using opnsense 18.

I followed the instructions given in this Wiki-Entry: https://docs.opnsense.org/manual/how-tos/transparent_bridge.html.
 But now i'm facing the same issues as the user amithad in this thread:https://forum.opnsense.org/index.php?topic=5162.0.

My setup:

Router with DHCP and NAT (192.168.1.x) ------> OPNsense -------> (192.168.1.x) Server.
I have 3 Nics and followed the tutorial step by step, despite of defining a management ip as stated in Step 4, because I don't need this due to a dedicated managment nic.
I added an any->any rule to EVERY interface but I still cannot pass traffic through the new bridge. Do I need to set a gateway for the bridge interface pointing to the router that is doing dhcp etc? I'm really stuck at this point and tried everything that has been stated in this forum to transparent firewall configs.

Is there anything that has changed from version 17.x to 18.x so that the tutorial fails?

For the records:
I am unable to tell you what I configured wrong. After two restarts the device works as described in the tutorial.
