have taken the time to construct a PIX config that will allow me to switch over to the Choice One DSL service. My IP's issued are as follows:
220.127.116.11 =original assigned before additional IP addresses were added
DSL config is the newest version for DSL, of course.
Subnet is 255.255.255.0
FIRST ATTEMPT AT LOADING THE CONFIG:
I tried to give my config a shot this weekend and did not succeed. I thought I had everything ready to go, but there is a mistake somewhere in my configuration. I just went ahead and reverted back to the cable connection and we are back up and running. I changed the subnet mask on the DSL config for the IP outside route to 255.255.255.0 according to my DSL documentation, but that was not it. I may have everything mapped incorrectly, from old to new. I am not sure.
Old Config (working)Cable connection:
evansville-pix# config t
evansville-pix(config)# interface ethernet0 auto
evansville-pix(config)# interface ethernet1 auto
evansville-pix(config)# ip address outside 18.104.22.168 255.255.255.248
evansville-pix(config)# ip address inside 172.22.2.253 255.255.255.0
Re: Configuring a Firewall as I am switching ISP's
I haven't done a indept analysis of your configuration, but I noticed that your mask for 22.214.171.124 was set to 29 bits instead of 24 bits. This causes the PIX not to perform proxy ARP for your static translations. Modify your mask and try it again. Let me know if this solved your problem.
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...
