Re: [expert] IPTABLES NAT script doesn't work in 9.0

[Jeferson Lopes Zacco]

yep it is. SainTiss told me that in the newbie list (thanks!). As I said, I can ping/resolve hosts fromthe client, but it does not transfer (large chunks of?) data. Weird. Perhaps it has smthing to do with msec?

Hi all,

I've been spending some time trying to migrate from MDK 8.1 to 9.0. I
faced numerous problems, but now there is one left which I can't figure out.

I have a script for IPTABLES which act as a firewall and doubles as a
NAT/MASQ for the other machine in my tiny network. The script functions
exactly as expected in MDK 8.1, which is still installed here (thanks
God!). I took the script from the IPMASQ-H2 and made some minor
modifications. It is attached here (pipe it trough a grep -v \# to get
rid of the comments).

The script does not work in MDK 9.0. It gets loaded, ip_forwarding is
activated, I can have DNS access from the masqued client - but the data
just does not get trough. I tried disabling most of the servers/services
in MDK 9 that I thought could have anything to do with it - like
prelude. The configuration of the network card/ppp interface is
identical, including MTU values. I guess there is some "wizard" from MDK
9 which is getting in the way. But I don't know what it could be.

Can somebody point me how can I solve this?


TIA,
Wooky.
