Hi all,

I have some problems with ipnat (I think).
The problem is that my firewall stops nat-ing my internal machines to
the internet after a while (let's say one week). I translate a C
class network to one internet IP address, with portmap, and ftp
proxy. Note that only my proxy and one ftp client is on this c class
subnet. Most internet connections are handled by my proxy(squid). The
problem stops after a ipnat file reload(and nat table reload)

The ipnat.rules file goes like this...
map xl1 10.1.50.0/24 -> xxx.xxx.xxx.xxx/32 proxy port 21 ftp/tcp
map xl1 10.1.50.0/24 -> xxx.xxx.xxx.xxx/32 portmap tcp/udp
10000:65000
map xl1 10.1.50.0/24 -> xxx.xxx.xxx.xxx/32

where xxx is my internet ip's.

Any advice?
Thanx.
