Josiah-- You can not add secondary IP addresses or aliases to a PIX interface, you need to use static NAT maps to use the other public IP addresses. All of the addresses must be in the same subnet, too. So you can have: ip address outside 4.147.128.90 255.255.255.248 static (inside,outside) tcp 4.147.128.91 smtp 192.168.20.12 smtp netmask 255.255.255.255 static (inside,outside) tcp 4.147.128.91 https 192.168.20.12 https netmask 255.255.255.255 static (inside,outside) 4.147.128.92 192.168.20.25 smtp netmask 255.255.255.255 The PIX will take care of proxy ARP for you. You can NOT have: ip address outside 4.147.128.90 255.255.255.248 static (inside,outside) tcp 5.147.128.91 smtp 192.168.20.12 smtp netmask 255.255.255.255 static (inside,outside) tcp 5.147.128.91 https 192.168.20.12 https netmask 255.255.255.255 static (inside,outside) 6.147.128.92 192.168.20.25 smtp netmask 255.255.255.255 On Tue, Jan 13, 2009 at 11:01 AM, Josiah Bryan < jbryan () productiveconcepts com> wrote:
Rather new to the advanced pix configs - I've been doing basic pix config/maint for the past 3 years. I've got 13 public IPs that are coming in thru a cable modem to my PIX. The fist IP is routing correctly, but I can't seem to figure out how to get the PIX to accept any of the other IPs that I've bought. Now, I'm used to the linux (redhat background) method if adding an alias to an interface, eg: ifconfig eth0:0 1.2.3.4 ifconfig eth0:1 5.6.7.8 .. and so on and so forth. Basically, is an equivalent operation possible with the PIX? (Running PIX ver 6.3(3)) (Of course, I'd like to be able to do static translation based on incoming IP, but I think I've got that line covered: "static (inside,outside) tcp 1.2.3.4 smtp 10.0.1.51 smtp netmask 255.255.255.255 0 0"). How do I add multiple "aliases" (for lack a better term) to the outside interface? Thanks in advance for your patience and advice.
