This is a simple HOWTO configuration for NAT on an Extreme Summit 48s

This assumes two VLANs an internal and external:

Nat Configuration

The steps to get NAT running are:

1. Add a NAT rule
2. Set the NAT timeout
3. Configure “internal” vlan(s)
4. Configure “external” vlan(s)
5. enable nat

Assuming you have an external vlan called “ext” and an internal block of IPs at 172.16.166.0/24 and an external address 198.168.0.10/32; you can use the following:

Configure a NAT rule

configure nat add “ext” map source 172.16.166.1/32 to 198.168.0.10/32

Configure the NAT timeout

configure nat timeout 300

Configure the internal VLAN for NAT

configure nat “webserver-internal” inside

Configure the external VLAN for NAT

configure nat ext outside
configure nat Default outside

Enable NAT

enable nat

That should be all there is to it. I hope this worked for you.
