I have a question about Static NAT.
My client use a Linux Firewall for Connection partners using L2L (about 70). He bought two 5520 to replace the current Linux Firewall. I conducted a survey of access rules for migration of the firewall and I have problems with some rules for nat statico. Today many clients connect to an external address static nat configured in Firewall for port redirection, but this by using multiple outside addresses to the same address inside. As we know there is a limitation to this configuration when using NAT on the ASA / PIX. Next example below:
static (inside,outside) tcp 22.214.171.124 80 10.10.10.10 netmask 255.255.255.255 80
static (inside,outside) tcp 126.96.36.199 80 10.10.10.10 netmask 255.255.255.255 80
Have any tips on how I can treat this type of NAT?
The client is even thinking about rolling back the purchase of Cisco ASA due to this limitation.
Can you help?
Thank you very much !!
