Need telnet access without NAT

vijaykumargowda — Mon, 11 Mar 2019 13:41:24 GMT

I have an issue with ASA 5510 Firewall.I have three interfaces X,Y and Z, where X has a security level of 0, Y=0 and Z=10.

I need to access hosts on Y from Z.As of now it works fine with NAT.All i want is to access hosts with no NATing.

I have applied an access list to permit telnet and able to see the hit counts

,but i see only a black screen.I tried changing the security levels and applying same-security-interface command,but didnt work.

Is there anything else which you would like to tell us on this issue.

Any help would be appreciated.

Regards,

Vijay

Vijay,

Try adding the following to your nat config:-

static (Z,Y) z.z.z.z y.y.y.y netmask x.x.x.x

or you could create a policy based no-nat....but try the above first.

Hello Andrew

The issue was with Internal routing.I added a route and it started working fine.

Thanks for your reply.
