There's two WAN nodes on cisco 28xx and 871 with 2 satelite hops between them. Link throughput is 64Kb/sec. Encryption with IPSec tunnel applied between routers. TCP sessions in such a scheme are very slow and applications goes timed out. All my tries of RBSCP tunnel with IPSec encription between routers gave me no success.
Have anyone here real experience of implementing encrypted traffic transmition over slow satelite links?
Where should I look for a solution? Try RBSCP over IPSec harder? Try WAAS or Juniper WX or others?
I have nothing against Juniper but would it work good?
