Connect several home networks with VPN

[nikki]

Hi,

I'd like to connect 4 home networks (mine and relatives).
All networks have asus routers with merlin FW. Every network connected to the different ISP.

First home has network 10.10.1.0/24, second - 10.10.2.0/24 and so on.

I'd like to them all together with VPN and have SMB and DNLA protocols work across all these networks.
I'm going to connect every router with openvpn or tinc VPNs, route packets between networks through VPNs and to run igmpproxy on the routers to proxy DLNA packets.

It it the correct and simplest setup, or some better way is possible?

Any luck with this???

Partial luck.

I setup tunnels in "router" mode without much problems.

I setup avahi reflector for mDNS, and that was easy part

/jffs/configs/avahi-daemon.conf.add
[reflector]
enable-reflector=yes

Now I'm route multicast traffic (including dlna/upnp) through the tunnels and that's the real pain. I want multicasts routing also work as usual with WAN. So I need some kind of cascading routing: multicasts from the WANs should go to corresponding home networks, but not across the tunnels. And multicasts originated from home networks should be routed through the tunnels.

igmpproxy does not support cascading setups. There is some alternative - pcproxy, that may be useful. At least its configs can describe cascading schemes. But I cannot make it compile for the router still. That's where I am now.
