In order to create a -more or less- representative test configuration, I tried to copy a real life situation into a xen-set-up:
-external firewal
-openvpn server
-Internal firewall
-management gateway
-asterisk pabx
-mysql server
To simulate different networks, I created dummy ethernet devices, and connected bridges to it.
All of the bridges are working OK, except ONE: BR2 (for setup, see attachement)
If i ping on the vpn-box (vpn is not setup yet) towards internal firewall or otherway round i see no traffic at all
( 172.16.100.1 => 172.16.100.2 OR 172.16.100.2 => 172.16.100.1)
Looked at [internal] firewall, at the bridges, routing, but i'm clue-less….
Test i've done sofar:
Any suggestion where to look next?
Kind regards, Hans
