Refer to document below, I have simple question about virtual telnet.
PIX/ASA : Cut-through Proxy for Network Access using TACACS+ and RADIUS Server Configuration Example
Is it possible to ping virtual telnet ip address?
I have one case where user unable to authenticate into virtual telnet. Normally he only need to authenticate to the virtual ip before he allowed to do other thing.
What happened is when he telnet into virtual ip, nothing happened and time out after a few minutes.
I did packet capture on the firewall and I can see SYN packet sent to the firewall.
Firewall reply with SYN ACK to the user.
However, there is no ACK packet from the user.
This SYN, SYN-ACK traffic keep repeating.
Any advise would be highly appreciated.
