We have two unix servers
Servers A : 10.10.10.2/ 24
Servers B : 192.168.1.2 /24
connected to routers Fa0/0 and Fa 0/1 interfaces respectively.
We have configured following access list
access-list 101 deny 10.10.10.2 0.0.0.0 192.168.1.2 0.0.0.0 eq telnet
permit any any
and applied as
( config-if)#ip access-group 101 in
This will deny telnet access initiated from 10.10.10.2 to server 192.168.1.2 as source , destinatio and target port numbers are matching.
What will happen if reverse telnet connection is initiated , that is telnet is initiated by 192.168.1.2 to 10.10.10.2 ?
Will it be denied by our access list ?
As packet returning back to 192.168.1.2 will match the ip address but I think target port will be diferent and not 23 ) so connection shoud be established.
Thanks in advance.
