====== Network-Bridges (BRIDGE0) ======

!!Note:!! This is outdated documentation, since AstLinux starting with 1.3.10 (07/2020) dynamically adds VLAN and BRIDGE entries to the interface list.

----

!!When you setup a software network bridge in AstLinux, you need to be careful to not lock out your network connection:!!

**Q:** When I enter

  BRIDGE0="eth0 eth3"

in the ''user.conf'' and reboot, why is then ''eth0'' not reachable over the network ?

**A:** If eth0 was on the external interface, you would also need to set (temporarily):

  EXTIF="br0"

**or** If eth0 was on the 1st internal interface:

  INTIF="br0"
  
in your ''user.conf''. Then after a reboot the (new) bridge will appear in the menu in the Network tab, select ''br0'' as normal and then remove the ''EXTIF'' (or ''INTIF'') entry in ''user.conf''.

I know, a little confusing, but it's the only way since we have nice little drop-down menus of the "current" active interfaces.

Remember with a bridge, only the ''br0'' is the "real Interface" the one you bring up and down and set IP address to.  NOT eth0 or eth3 .

Finally, be aware that software bridging carries a non-trivial performance penalty.  The maximum throughput will be reduced by at least 15% with a software bridge in the path.
