I havn't seen any other posts on the list for this problem with Konqueror not 
being able to access the gateway, but this what I found.

After some recent Etch updates the boot up messages said 
that /etc/network/options was deprecated, and to read the README  for 
netbase, which is in /usr/share/doc/netbase/README.Debian. Did this, and 
added the following to /etc/sysctl.conf. See below.

This file is deprecated, and if present should be replaced by values
in /etc/sysctl.conf or equivalent custom scripts.
The relevant sysctl values are:

ip_forward=yes:   net.ipv4.ip_forward = 1
spoofprotect=yes: net.ipv4.conf.default.rp_filter = 1
                  net.ipv4.conf.all.rp_filter = 1
syncookies=yes:   net.ipv4.tcp_syncookies = 1

So I did that, and renamed the options file in /etc/network/options.

I admit that trying to resolve the problem that turned out to be a zeroconfig 
one, I'd messed with network settings, but my original user was still able to 
access the Internet with Opera, and Firefox, and no problems getting updates 
via the CLI and apt-get, nor was there any problem using KDE's superuser 
filer manager in webbrowsing mode accessing the Internet. Only Konqueror 
could not access the net.

Someone on the KDE list suggested creating a new user, so I did that, and now 
Konqueror works ok.

thinking about this a bit, and skipping some trial and error stuff I comment 
out the new lines in /etc/sysctl.conf, and rename /etc/network/options 
to /etc/network/options. Now logged into the new user Konqueror cannot access 
the net. so I again rename /etc/network/options 
to /etc/network/options-deprecated, and uncomment the 4 lines 
in /etc/sysctl.conf. Now logging into the new user Konqueror again works ok 
in accessing the Internet.

Still no joy with Konqueror with the original user. 

As a last resort, and skipping some more stuff I tried, I rename .kde while 
logged out from the original user, then log back in to original user which 
creates a new .kde. Icons are all over the place, but Konqueror now accesses 
the Internet ok.

I don't really know what caused the Konqueror problem for the original user, 
but seems to have something to do with moving /etc/network/options entries 
to /etc/sysctl.conf. 

I havn't been on the Debian list long, but has anyone else seen anything like 
this?
