I had a problem when i deleted an access-list. The GUI interface is deleting me de route associate whith the IP invoved in the access-list. This is the output in my syslog server when i deleted the ACL:
Dec 5 16:24:21 192.168.157.1 : %PIX-5-111008: User 'jvega' executed the 'no route genesis 10.252.252.128 255.255.255.192 192.168.157.4 1' command.
Dec 5 16:24:21 192.168.157.1 : %PIX-5-111008: User 'jvega' executed the 'no access-list Desa_access_in extended permit tcp host 10.251.251.18 10.252.252.128 255.255.255.192 eq 21' command.
No, it is expected result. If you remove any access-list especially which was created to allow/permit traffic from particular destination, then the basic characterisitic of firewall comes into effect that is by default all the traffic from the outside networs blocked.
Cisco might label it a feature, but we users call it a bug. All Cisco's GUI configuration tools have similar problems... they get a little sloppy about deletions and changes. As a general rule, don't use a GUI for simple tasks. And always inspect what the tool wants to send to your router *before* it send it.
(In Cisco's defense, the tools usually warn you when it's going to do far more than you just asked it to.)
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
