Hi Friends,

Actually I have a firewall running RedHat 8 with almost the latest 
kernel (from RH).
The interface eth0 has many aliases and there is a nat rule:

iptables -t nat -A POSTROUTING -s 10.x.x.x/16 -j SNAT --to-source 
200.x.x.10-200.x.x.21

(200.x.x.10-200.x.x.21 are IP aliases)

Everthing works fine, but when I try to do the same on RedHat9 (other 
box) running the latest kernel it doesnt works. Only works with the IP 
address of the interface (no alias), like this:

iptables -t nat -A POSTROUTING -s 10.x.x.x/16 -j SNAT --to-source 200.x.x.9

What is happening? why dont works SNAT with aliases? or maybe is not a 
netfilter problem?


Thanks in advance.

Geffrey Velásquez.
