PIX 515:HOWTO telnet from DMZ into INSIDE?

[dasa123]

Dear experts,

we are using CISCO's PIX 515 and want to telnet from
a DMZ system (IP 149.243.236.67) to a Sun server lo-
cated in the INSIDE region (IP 149.243.236.34):



149.243.236.98 (OUTSIDE)
------------------------ 149.243.236.32/27
| PIX 515 | 149.243.236.33 (INSIDE)
| PAT: 149.243.236.99 | ------------------------- Sun system
| |
149.243.236.34
------------------------
149.243.236.64/27
149.243.236.65 (DMZ)

Client
149.243.236.67


And this is our PIX configuration:

As I told you (from the client 149.243.236.67)

%telnet 149.243.236.34

is not working, the "debug icmp trace" says:

Deny inbound tcp src dmz:149.243.236.67/45112 dst
inside:149.243.236.34/23 by access-group "acl_dmz"

What's wrong here in my config?

Many thanks in advance for tips, glues!

Your problem is in this acl:

access-list acl_dmz permit tcp any host 149.243.236.93 eq telnet

But you are telneting to:

%telnet 149.243.236.34


This isn't allowed by your acl!
