[SR-Users] Problems with TCP

[Daniel-Constantin Mierla]

Hello,

for 1) Is the device behind nat? Do you have tcp connection lifetime 
parameter value long enough?

for 2) is the physical IP a public space IP? Do you have mhomed 
parameter set? It is a warning saying that the interface returned by OS 
for connecting to the destination is not in the listen list.

for 3) yes it is expected behaviour, you just need to do record routing 
as usual, nothing special.

Cheers,
Daniel
