the problem of NAT gateways of our LAN (PSE-A + PSE-B)

[Emin Gabrielyan <emin.gabrielyan@switzernet.com>]

Christian, Kerim,

I suspect that the strange problem comes from the fact that in PSE-A the 
Swisscom router is a kind of a central switch. Offices and other 
switches are interconnected via the switch integrated in this router. 
All cables of different parts of LAN shall be connected to a neutral 
switch. The Swisscom router must be also connected to that neutral 
switch as an appendix (no other LAN part must transit via Swisscom 
router). I hope that after this, the problem will be solved.

Please do it, maybe today, because anyway the day is lost due to STEG

Emin

This doc must be updated once the LAN works properly
- add the missing screen shot with the VTX in PSE-B
- add the diagram of our network [gw EPFL] -- [gw VTX] -- [gw Swisscom] 
--- LAN PSE-A [bridge] ---- [bridge] LAN PSE-B --- [gw VTX]
- specify the connection parameters (upstream/downstream/monthly fees)
