Can I pass 802.1q (VLAN tagged) through a VPN TincinHUB/Switch mode?.

[Ramses II]

Hi Peter,

I say "trunk" from the standpoint of CISCO "Trunk Port = port that belonging
to several VLANs. From the standpoint of other manufacturers "Trunk Port =
port that sum  the bandwith of several interfaces.

Becouse this, I have created those interfaces:

eth0.5 and eth010

And I have ping to the PC in both VLANs. But if I add to bridge, for
example, the eth0.5 and tap0, I haven't ping to the PCs in the VLAN 5.

¿Do you know the WRT54GL router and the OpenWRT firmware?. I think that here
is my problem, that I don't well know how to work with Tinc and this
router/firmware.

I think that if I will installed all in two PCs with linux, all be work
fine, but I need work with this routers.

I am relying in this:

Sorry if my english isn't very good...


Best regards,

Ramses
