How can i add interface to two bridge?

[Sob]

If you add IP address to bridged interface, you can access it just fine. But traffic will no longer look like it comes from/to that interface, the bridge interface will be used instead. Why is it allowed? I don’t know, probably because it doesn’t really break anything, even though it might be a little confusing.

Your main problem seems to be that you can’t touch ESXi settings. Otherwise suggested solution with different VLANs for each ISP would be a simple and clean one.

Anyway, what exactly are you trying to do with firewall? Why NAT, when the point of this exercise was to get public addresses to servers (or at least it gave that impression to me)? Where the LAN comes from, is that some additional private network? If so, how and where it’s connected?

You need to put a vlan in each bridge - and bridge this with the third bridge.

still - my first post. to bridge bridges - add some vlan to the bridges you want to bridge. And bridge the vlan in a new bridge. This is a bit off box thingking, compared to cisco etc - but soooooooooo much more managable. if you add a vlan. a vlan is just a vlan. And can be the same vlan manny times. The macic just happen when vlan is bridged. In other system. Once you add a vlan. you add a vlan… and its like "ah. you add the same… we automaticly bridge… even if thats not what you want.

I tried this: create vlan1 on interface bridge1; create vlan2 on interface bridge2; create bridge3; add vlan1 and vlan2 to bridge3.
THIS NOT WORK!
