[manet-dlep-rg] Example: TCP server on satcom modem

[Teco Boot <[e-mail]>]

I verified operation of a telnet server on a old type BGAN terminal (E500).
It is compatible with 3GPP TS 27.007.
It is multi-hop unicast reachable from routers and other node types. 
Multiple connections can be same source, same destination. Think of NAT. Interfaces on my routers pointing towards Internet have NAT.

Although 3GPP TS 27.007 is a standard, the satcom extensions are not. 
For LTE, it doesn't look much better.

Attached a screenshot with two active 3GPP TS 27.007 sessions.
Device provides IP address and default gateway. But SQ is zero, it is in pointing mode. So it is a blackhole.
Having DLEP on this type of equipment would help a lot.
