[LARTC] multiple subnets and nat in one LAN

[Konrads]

<PRE>Here is the situation:
I have 2 subnets with real addresses and one with local (fake, 10.x.x.x).
So for local ones i do nat'ing to one real address. When i had only one &quot;real&quot; subnet i could settle with : 
iptables -t nat -A POSTROUTING -s ! realnet1/mask -j SNAT --to ipaddr-nat

so, right now, when i have two i have to do something like:

iptables -t nat -I POSTROUTING -s 10.0.0.0/24 -o eth1 -j SNAT --to ipaddr-nat
eth1 is link trough wich nat'ed ip's go out.
Q: Is this ok? My concern is about messages like this:

64 bytes from realipaddr2: icmp_seq=1 ttl%5 time$6 usec
&gt;<i>From gw (10.0.0.1): Redirect Host(New nexthop: realipaddr2)
</I>
