Loosing connectivity after a few days

Markus_de
Hello,

I have ASL 3.216 and an old Pentium I.
On ASL ist running the proxy and I've got set a rule which allows POP and SMTP. ICMP-forwarding is also allowed.
After 1 or 2 days, I can't reach the eMail-Server. But I can surf over the proxy.
The Pings to my mail-Server are lost, too.

After Rebooting the ASL, I can Ping and reach the pop and smtp again.

What could it be?

Thanks
Markus

    Hi Kerstin,

    after the last rebbot, I've configured a new rule.
    (Drop any from any to 255.255.255.255)

    Now, the period of running without failure was nearly two weeks.

    Today, the error occured again.
    I looked at the TCP-Pakets with TCPDUMP on the interal eth and could see, that the POP3-Paket could go outside. But no answer arrived.
    The liveLog did not register new entries while try to get new mail :-(
    After a new reebot, it works fine.

    regards
    Markus
