These two problems look the same to me and I have/had a third.  Dose any
one know if these issues were resolved and if there is a problem with
Debian's or Linux's iptables?  I'm thinking something in a recent update,
two weekes past, has caused this.  Many other ppl may be effected but are
unaware or not using iptables.

This should be a BIG RED FLAG!!!
