M-1 NAT on USG20

Postby holtain on Mon Jun 19, 2017 5:47 pm

I'm trying to replace our venerable Zywall 2 plus and these are the NAT rules I'm trying to setup on the USG20, and ideas how to do the M-1 ones?
Local Start IP Local End IP Global Start IP Global End IP Type
10.0.0.254 N/A 217.146.109.190 N/A 1-1
10.0.0.1 N/A 217.146.109.179 N/A 1-1
10.0.0.2 N/A 217.146.109.181 N/A 1-1
10.0.0.3 N/A 217.146.109.178 N/A 1-1
10.0.0.4 N/A 217.146.109.180 N/A 1-1

For the outbound source NAT(SNAT), you need add policy route rule.
Take your example,
10.0.0.7 10.0.0.15 217.146.109.184 N/A M-1
The source IP 10.0.0.7-10.0.0.15 go out to WAN, the source IP will be translated to 217.146.109.184

Here the steps,
1.Create source IP address object for 10.0.0.7-10.0.0.15
Go to GUI, Object > Address. Add an object with RANGE type, give a name, and the address - Starting IP address: 10.0.0.7, End IP Address: 10.0.0.15

2.Create public IP address object for 217.146.109.184
Go to GUI, Object > Address. Add an object with HOST type, give a name, and the address 217.146.109.184

3.Create policy route for SNAT
Go to GUI, Network > Routing > Policy Route. Add a rule.
Incoming: any (or you can select the interface of the IP 10.0.0.7)
Source address: select the address object created in step 1
Destination address: any
Next-hop: select the WAN interface (wan or wan_ppp if using PPPoE connection)
Source Network Address Translate: select the address object created in step 2
