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.
