iptables -t nat -D POSTROUTING 1
iptables -t nat -I POSTROUTING -p all -s 10.8.0.0/24 ! -d 10.8.0.0/24 -j SNAT --to-source Y.Y.Y.Y

Можно до одной строчки утрамбовать:

iptables -t nat -R POSTROUTING 1 -p all -s 10.8.0.0/24 ! -d 10.8.0.0/24 -j SNAT --to-source Y.Y.Y.Y

iptables-save -f rules.v4
vi rules.v4
iptables-restore rules.v4

man iptables-save/restore еще не помешает.
