Router vs bridge mode

[mikeg77]

Can anyone give me some solid examples of why it is better/worse to use bridge or router mode?

Thanks!

I'm not sure of it being a matter of better or worse, but what you are trying to accomplish. For instance on my network, I already had a Sonicwall handling the router role and I am simply using Untangle as a "heavy-duty filter".

What is the layout of your current network?

Generalize: To use router mode when UT is edge of your networks. To use bridge mode when UT is on inside of your other router edge device.

Think router to connect separate networkings - your and ISP. Router have IP address on both NIC.

Think bridge, is transparent, to invisibly connect parts of one same network. Bridge have not IP address on NICs. Have IP address inside it - management address.

What about stability etc? I can see why it would be better(especially in larger environments) to use in bridge mode, but what about smaller networks? is there a performance gain in either? Is the router reliable? I've read a few post where the router module is dropping connections and i myself have not been able to get the newest version to connect to my FIOS PPOe.

I hope I am not hijacking this thread, but it seems to appy here.

Can I use the OpenVPN when in the bridge mode?

I had to setup in bridge mode, because my company's modem / router is already providing NAT, and I could not seem to get a double NAT to work to act as a router to an inside network. Also, did not see any place to set up a routing protocol (RIP V1, or V2).

Anyway, I am using it in bridge mode to provide the extra firewall and protection services, but need to use the VPN as well. I have done port forward on 1194 and allowed the outside IP access, but when trying to send an email with client VPN data, it never goes through and when trying to save as usb file it gets an error "cannot save".

thanks

The answer is yes. You can have openvpn in bridge mode. Ofcourse, openvpn itself can also be in bridge mode but untagle default is router mode. I hope that I have not confused u.
