I have a simple setup Cisco virtual router in ESXi host and talk to Cisco ISE on TACACS.
This is just a regular VM vSwitch.
R1 G0/0 172.16.100.90/24 <-> ISE (172.16.100.104)
R1 loopback0 150.1.1.1/32
They both able to ping each other but for some reason it won't able to communicate port #49 when source from R1's loopback0.
Any idea?
IOS-R1#telnet 172.16.100.104 49 /source-interface gigabitEthernet 0/0
Trying 172.16.100.104, 49 ... Open
[Connection to 172.16.100.104 closed by foreign host]
