Hello!
I have lan network like 10.10.0.0/16 and two sets of external addresses
like 1.1.1.0/24 and 2.2.2.0/24. How to perform nat to use all my
external addresses? Now i have rules like
add rule ip nat POSTROUTING oifname "vlan3" ip saddr 10.10.0.0/16
counter snat to 1.1.1.0-1.1.1.255 persistent
add rule ip nat POSTROUTING oifname "vlan3" ip saddr 10.10.0.0/16
counter snat to 2.2.2.1-2.2.2.255 persistent
But,as expected, only first rule works. I need something like this:
add rule ip nat POSTROUTING oifname "vlan3" ip saddr 10.10.0.0/16
counter snat to 1.1.1.0-1.1.1.255,2.2.2.1-2.2.2.255 persistent
But it is not supported.
Also, i've tried to use names sets like this:
add set ip nat ext_addr {type ipv4_addr;Â flags interval;
elements={1.1.1.0-1.1.1.255,2.2.2.1-2.2.2.255} ;}
But
nft 'add rule ip nat POSTROUTING oifname "vlan3" ip saddr 10.178.0.0/16
counter snat to @ext_addr persistent'
Error: unknown raw payload base
add rule ip nat POSTROUTING oifname "vlan3" ip saddr 10.178.0.0/16
counter snat to @ext_addr persistent
With all respect!
