ASA 5520 firewall with L2L vpn configured.

Hi all,

I have configured the ASA 5520 firewall with L2l VPN. Everything working fine but whenever I connect the pc to the Management Interface then all the vpn sessions are terminated.

What could be the workaround for this issue.

Thanks

Thanks for your reply.

The Management Inteface is in 192.16.1.0/24 network range with PC ip add is witin this range.

The crypto ACL is in 172.0.0.0/24 range. This management interface is only fo management purpose only.

How is it possible that the pc conneced to the Management Interface cause  all the VPN terminate immediately.

Tomorrow I am going  site to troubleshoot this problem.

Hello,

Which version of code is your ASA running ?

Can you use the PC on the other end of tunnel just fine or the issue is recreated ?

Could you attach a show tech-support  from ASA so that we can have a look at the config ?
