broadcast forward

RouterOS General
1

Hi to all
i have a big problem
my radio amateurs friends like to use CT log program by K1EA
program have -enet option to broadcast on local area network on
255.255.255.255:3030 UDP

what i try is to setup mikrotik router with public ip for some kind of VPN (pptp,l2tp,ovpn whatever) to serve as bridge, vpn concentrator

and a few XP with CT program and VPN connection to connect with mikrotik

i try this setup and thing does not work

have 3 client connect with pptp, 192.168.0.x/24 everithing working great but no UDP broadcast.

is there any way to pass UDP broadcast from one VPN to other
or to form VPN bridge closed group and to broadcast inside this group?

or if broadcast everithing is imposible, then some trick to catch only :3030 UDP packets and force retransmissinon on othet VPN connections ?

tnx in advance

I do something similar for Wake On LAN broadcast forwarding:

First, I create an static ARP entry to resolve an IP to broadcast MAC:

/ip arp
add address=192.168.101.254 comment="" disabled=no interface=LAN mac-address=FF:FF:FF:FF:FF:FF

Then, I create a NAT rule to forward to that IP:

/ip firewall nat
add action=dst-nat chain=dstnat comment="Wake On LAN" disabled=no dst-port=7000 protocol=udp to-addresses=192.168.101.254 to-ports=7

First, I create an static ARP entry to resolve an IP to broadcast MAC:

nope, this does not work for VPN

any solution?

What about creating an EoIP per VPN then create a bridge, including all your EoIP tunnels as ports in the bridge?
This of course, would require Mikrotik on all VPN clients and VPN servers.
