Bojan,

why don't you try to upgrade to a more recent version of iptables and if
possible to a more recent kernel ? You know, just in case...

I have a setup similar to yours (except from POSTROUTING which is of
type MASQUERADING rather than SNAT) and it works all right.

Also, have you checked other parameters such as TTL ? What about ICMP ?
You can enable ICMP with the following rule:

-A INPUT -p icmp -j ACCEPT
