PAT Address | 128.118.202.254
PAT = Port Address Translation. This is similar to how SNAT works with iptables. A single public ip. This is preferred to just straight NAT, which on the ASA is one-to-one with a set translation expiration time. After the global IP range is used up, further outbound connections are dropped. A single PAT address supports up to 65,536 outbound connections (TCP sessions).
NAT config on ASA:
global (Outside) 1 128.118.202.254 nat (Bioinformatics) 1 192.168.2.0 255.255.255.0 nat (Bioinformatics) 1 192.168.4.0 255.255.255.0 nat (Bioinformatics) 1 10.1.0.0 255.255.0.0
