ESXi 6.7 Cisco TACACS issue....

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#

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]

IOS-R1#telnet 172.16.100.104 49 /source-interface loopback 0

Trying 172.16.100.104, 49 ...

 

 

ISE1/admin#

ISE1/admin#

ISE1/admin# ping 150.1.1.1
