Vyatta 6.4からはコマンド体系が一部変わったみたい。
6.3まで
set service nat rule 1 type masquerade set service nat rule 1 source address 192.168.0.0/24 set service nat rule 1 outbound-interface eth1 commit save
6.4以上
set nat source rule 1 translation address masquerade set nat source rule 1 source address 192.168.0.0/24 set nat source rule 1 outbound-interdace eth1 commit save
So, what do you think ?
