Hallo zusammen,

 

ich bin noch ein absoluter Neuling in Sachen PIXen.

Aber ich habe mich ein bissl in die Thematik eingelesen und habe mir ein kleines Test Szenario aufgebaut..

 

Client A

192.168.0.2/24

 

PIX_A (501)

OutsideIP 172.27.0.1/24

InsideIP 192.168.0.1/24

 

from

[...]

to

 

Client B

192.168.1.2/24

 

PIX_B (501)

OutsideIP 172.27.1.1/24

InsideIP 192.168.1.1/24

Ich kann die PIXen leider untereinander Outside to Outside nicht erreichen..

Auch von Client A to Client B funkt der ping nicht...

 

Was mache ich falsch?

Könnt Ihr mir ein bissl auf die Sprünge helfen, ich möchte keine fertige config, sondern nur Hilfestellung...

[mupp 10]

ich habe jetzt ein bissl an meine ACL gebastelt.. die PIXen sind jetzt untereinander erreichbar.. PIX to PIX...

 

Ich möchte jetzt aber das Client A to PIX_B outside per ping erreichbar ist..

Wie mache ich das..

 

Hier die Config PIX_B

 

access-list outside permit ip 172.27.0.0 255.255.255.0 any
access-list outside permit icmp any any echo-reply
access-list outside permit icmp any any unreachable
access-list outside permit icmp any any time-exceeded
access-list inside permit ip 172.27.0.0 255.255.255.0 any
access-list inside permit icmp any any echo-reply
access-list inside permit icmp any any unreachable
access-list inside permit icmp any any time-exceeded
access-list inside permit ip 192.168.0.0 255.255.255.0 any

 

ip address outside 172.27.1.1 255.255.255.0
ip address inside 192.168.1.1 255.255.255.0

 

Hier die Config PIX_A

 

access-list outside permit ip 172.27.1.0 255.255.255.0 any
access-list outside permit icmp any any echo-reply
access-list outside permit icmp any any unreachable
access-list outside permit icmp any any time-exceeded

access-list inside permit icmp any any unreachable
access-list inside permit icmp any any time-exceeded
access-list inside permit ip 192.168.1.0 255.255.255.0 any
