Adding bridge -> nothing happens

voluhar · Aug 4, 2011, 10:15 AM

Hello everyone.

I want to set up bridge between two interfaces (LAN and OPT2). I read some topics, but without success.
When I go to >Interfaces>assign>bridges and I select two interfaces and then click save, it is everything like it was before. There is no new bridge.

Firmware version: 2.0-RC3 (i386) built on Wed Aug 3 19:24:43 EDT 2011
Both NICs are Intel Pro 10/100/1000.

LAN interface: enabled, static IP and DHCP enabled
OPT2 interface: enabled, none
Can somebody help me with this problem, because I don't know what to do.

Here is system log:

There seems to be some issues with your interfaces there!

From memory, what you have done is just create the bridge and you still need to go back to Interfaces -> (assign) and click on the "+" button to add the newly created bridge interface to the list of interfaces available to pfSense.

Your log output reports a failure adding the two member interfaces to the bridge: devices reported busy. Maybe it would be worth rebooting so the bridge can have its members added early in the system startup.

Actually I can't create a bridge…

It is something really strange happening with my pfSense. I will play with it tomorrow, factory default and then fresh install.

I rebooted it (some times) and I can't even change network port on interface, like it wont save changes. In system log is nothing useful for me about that.

If I create enough interfaces that I got 2 vlans for OPT6 and OPT7, and try to create is system log like this:```
Aug 4 21:29:05 check_reload_status: Syncing firewall
Aug 4 21:29:05 kernel: rl0_vlan102: promiscuous mode enabled
Aug 4 21:29:05 kernel: rl0_vlan101: promiscuous mode enabled


Probably is playing with that install waste of time but if anybody need that I try something before factory default just tell me.

Maybe related to the same problem I have with assigning interfaces? See: http://forum.pfsense.org/index.php/topic,39588.0.html
It will be fixed in a new snapshot, I will certainly try.

I read your topic while system was updating to 2.0-RC3 (i386) built on Thu Aug 4 12:47:50 EDT 2011.
So after updating problem was solved.

Just one more question… Is it normal that you have to reboot if you want to apply changes?

eri-- · Aug 5, 2011, 5:21 PM

What is the reason you have to reboot?

wallabybob · Aug 5, 2011, 10:19 PM

It has been my experience that most changes don't need a reboot to take effect. One exception I can recall (but this was months ago and I'm not sure of all the details): I changed my LAN IP address to a different subnet and then couldn't access the web GUI. I rebooted. I suspect I could have avoided the reboot if I played around a little more.

Firewall rule changes sometimes need a little dance to take effect - see Diagnostics -> States, click on the Reset States tab and read the explanation.

I was reading this http://forum.pfsense.org/index.php?topic=20917.0

1. Start box with WAN1 (vr0) - PPOE, WAN2(dc0) - DHCP, LAN(em1) - stattic
2. Add OPT2(em0) and OPT3(rl0) interface
3. Enable OPT2 and OPT3 interface, apply changes
4. Create bridge OPT2 + OPT3
5. Selecet BRIDGE0 as LAN port and em1 as OPT3 port
6. Save settings

So at that point I had to reboot If I want working network.

I can not stress it enough.

You can assign the bridge as anything else with the same results it is not necessary for it to be LAN!

I hope that we understand each other…(and that my English isn't to bad)...

Well It isn't clear to me why I had to restart pfSense at point 6. Because before system restart pfSense doesn't respond to ping and after it does. After restart I doesn't change anything.
Maybe should be there checkbox or something to enable automatic restart if it is needed.
