https://community.extremenetworks.com/t5/extremeswitching-other/s-series-nat-ressource-limit-quot-ip-address-quot-nat-strategy/m-p/10424#M1452 Hi,<BR /> I have a question about NAT. We have currently 3500-4000 wireless users with official external IP<BR /> Adresses in four VLANs. Since the number of our wireless clients is rising, we will <BR /> run out of official IP Adresses for wireless purposes. So we want to <BR /> give our wireless users internal addresses (192.168.x.y) and dynamically<BR /> map them to a pool of external addresses.<BR /> <BR /> One can read the following table in S-Series Configuration Guide (Table 42-2 NAT Resource Limits):<BR /> Global Bindings: 65536<BR /> IP Addresses: 2000<BR /> Pools: 10<BR /> Port Mapped Addresses: 20<BR /> <BR /> What exactly does the number "IP Addresses" refer to? Does it mean no more than 2000 internal IP-Adresses can be NATed per S-Series Chassis?<BR /> And what would be my outside NAT-Interface? Since I want to NAT between [wireless users vlans] (inside) and [internet](outside) and [alll other corporate networks](outside) wouldn't have to be almost every other VLAN an outside NAT-interface? Any ideas are welcome.
