Can Ice deal with this ?

[rc_hz]

Suppose there are three servers: A/B/C. Now I want to do this:
1.A get a proxy of B: BPrx
2.A passes BPrx to C
3.C makes a callback to B by BPrx.

Can this be done in the following three different network circumstances:
1.A/B/C is located in the same private network
2.A/B is in the same private network, while C is in the other private network. Before C, there is a Glacier2router
3.A is in a private network while B/C in the other private network. Before B/C, there is a Glacier2router.

I am just curious about this. Thank you!

Yes to all three questions.
