 ====== Network-Bridges (BRIDGE0) ======
-When you setup a network bridge in AstLinux, you need to careful to not lock out your network connection:
+!!Note:!! This is outdated documentation, since AstLinux starting with 1.3.10 (07/2020) dynamically adds VLAN and BRIDGE entries to the interface list.
-**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):

 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.
