how to use Relay to connect peers which are unreachable. (General questions)

i purchased soucecode license and use the WODVPN to connect peers under different network.

in some network environment, the peers cannot reach each others.

i had 3 peers A, B, C (3 PC in 3 diffirent netowrks, all have NAT and router on the gateway)

now after search method, the A can connect to both B and C, and B,C all can connect to A.

but B cannot connect to C, C cannot connect B.

it is confuse, i think if one peer cannot be reached, all peers shouldn't be able to reach it, right?

i just want to confirm is my case is normal or it is unnormal?

then if it is normal, any resolution can make the B and C communicate to each other?

i've tried to set the UseUpnp, but still not working in B and C.

can i use the CVPNRelays to let the both peers connect to a public server first? to make them communicate using the server?

if can, how to use this Relay class?

in what timing i can call to add a CVPNRelays to the WodVpnCom instance.

i'm using VC, and Com version.

can you just give some hints is ok, thank you very much?
