don't work telnet client from ssh session ("%Connections to that host not permitted from this terminal") in 151-4M.

I changed IOS to 15.1.4M in the ISR router.

If I connect to console by ssh and  I type  "telnet X.X.X.X YY"  in console then It appear the strange message "%Connections to that host not permitted from this terminal".

After I  downgraded to  ios 12.4.24 , then it's all work fine .

configuration line vty :

line vty 0 4

transport input ssh

transport output all

What it's the problem in IOS 15.1.4M?

Thank you for answer.

I've created the access-list :  access-list 20 permit 192.168.200.0 0.0.0.255

line vty 0 4

access-class 20 out

transport input ssh

transport output all

IF I try "telnet 192.168.200.2 " - It's working

But IF I try "ssh 192.168.200.2 " - It isn't working, appear "%  Connections to that host not permitted from this terminal" 

IF I try from router with IOS  12.4.23 - It's working fine .

Probably caused by bug ID CSCts95370

Removing/modifying the inbound ACL on the VTY lines of the device I was attempting to SSH from fixed this. Something causes the inbound ACL to actually function in both the inbound and outbound directions.

This helped me also, trying to jump thru a old 2900 to fix something, and this was stopping me, removing inbound ACL let me ssh out!!!
