I have configured an ASA 5510 at our data center. The problem I am facing is that in the network range of 0 to 255 there are servers with /24 masking and these are already routed by the router. I want to deploy the ASA firewall only to 6 of these servers which currently have the address from .9 to .14 and the firewall has the address .8 on its internal interface. How should I deploy or further subnet the network of /24 so that these 6 servers can be routed through the firewall instead of the router.
1) If you don't want to readdress your servers you could use the ASA in transparent mode and place the 6 servers in one vlan and leave the rest of the servers in the original vlan. Note that your are using 2 vlans but the same IP subnet and the ASA bridges between the 2 vlans.
2) Create a new subnet for your 6 servers plus the ASA ie. a /29 or /18 subnet would do the trick but obviously you now need to readdress both your servers and the inside interface of the ASA.
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...
