Adding the Cisco PIX 501 hardware firewall to an existing hosting account may result in problems with the external resolution of new domains. When a new domain is created through Simple Control Panel, a DNS zone record is created that associates the domain with the Simple Control Panel IP. When the Cisco PIX [...]
Translation rules must be added for all new IP addresses. When the Cisco PIX 501 hardware firewall is installed, the translation rules for existing IP addresses are created automatically.
For each new IP address, you create two static translation rules, one outside traffic and one for inside traffic.
