Assuming you have access to forward ports, you could forward a whole bunch of ports to the different machines so you can ssh directly to the hosts. Forwarding port 2222,2223,2224,2225,2226 for example to port 22 of each machine.
hostaddr.domain.x:2221 ==> Host1:22 hostaddr.domain.x:2222 ==> Host2:22 hostaddr.domain.x:2223 ==> Host3:22 hostaddr.domain.x:2224 ==> Host4:22 hostaddr.domain.x:2225 ==> Host5:22
Then when you ssh, you would just connect directly to the hosts with -
csshX -l user hostaddr.domain.x:2221 hostaddr.domain.x:2222 hostaddr.domain.x:2223 hostaddr.domain.x:2224 hostaddr.domain.x:2225
