UTM 9.502 Lag0 + RED15 Bridged

seroal

Hi all,

 

I need some help, because I´m creating a special setup for the first time. In this project the firewall does all the routing. So we have an etherchannel interface as trunk (many vlans on it) from the firewall to the coreswitch. There is also a remote site, connected via RED15. I now want to be able to use the vlans/ip configs, configured on the lag0 interface, also in that remote site. Is that possible to bridge the red and the lag in some way? The clients in the remote site, should feel, as if they were located in HQ from the logical point of view. Of course, they will never because of the lower speed.....

 

Did anyone built this before? How does it behave? Any problems with broadcasts? We have a few /24 subnets.

    Sebastian, I  don't understand what you would expect to gain from this.  The most I can see that you could do is to bridge the reds# Interface with an untagged Interface on the LAG.

    Hi Bob,

     

    if possible, I would like to use the same IP Network in a different location. But as I talked with my distributor today, bridging a red and a LAG Interface is not working. Probably it would work, when bridging an simple ethernet interface with the red interface....

     

    Or do you have any idea?

    "if possible, I would like to use the same IP Network in a different location."

    How about a simple stick diagram, Sebastian - one with a concrete example?

    Hi Bob,

     

    I hope you understand my problem now:

     

     

    In this case (indepent how much sense it makes) I would like to use vlans from HQ in Branch1. The L3 Interfaces in HQ are all configured on the UTM9 Firewall. Is there a possible way to get the Lag0 VLAN Interfaces bridged to the branch?

     

     

     

     

    Thanks,

    Sebastian

    That's what I thought you meant, Sebastian.

    I know it's possible without a LAG, But I can't "see" how a non-VLAN RED device would know how to manage this.  A VLAN switch behind the RED might work...

    This would be a good question to pose to Sophos Support.

    Cheers - Bob
