OPENVPN TAP

[Eleander]

Seeing my other posts where unanswered I'll try again from the start.
Got two sites where a VLAN needs to communicate with eachother but multicast needs to pass and clients need to reside within the same subnet. Seeing multicast and single subnet all I can do is use OPENVPN TAP? or GRE within IPSEC?

Set up is like this
VOIPVLAN100 int ip 172.18.100.33/24
OXO on that VOIPVLAN100 with IP 172.18.100.40/24 and GW PFSENSE IP

Other side
VOIPVLAN100 int ip 172.18.100.97/24
Client IP 172.18.100.98/24 which needs to connect to OXO

Server side config:
dev ovpns1
verb 1
dev-type tap
dev-node /dev/tap1
writepid /var/run/openvpn_server1.pid
#user nobody
#group nobody
script-security 3

On both sides I created an interface called OPENVPNBRIDGEVOIP which has the "ovpnc1" interface and I bridged this interface with the VLANVOIP interface.

Pings from client network to main network fail although firewall rules exist to allow all to all traffic.

Should I under the created bridge set a PTP selected interface?
I've been looking into this issue quit some time now and I can't seem to find a solution.

When I ping from one network to the other (pfsense ping) over the bridged interface I can reach other clients, but I can't reach the VLAN ip on the pfsense.
Nor can I ping from the VLAN interface to the other VLAN interface….

Is there nobody who can help me out? :-[
