-A PREROUTING -d 10.168.61.237/32 -p tcp -m tcp --dport 443 -j REDIRECT --to-ports 8443
-A OUTPUT -d 10.168.61.237/32 -p tcp -m tcp --dport 443 -j REDIRECT --to-ports 8443
COMMIT
# Completed on Thu Jul 14 09:33:54 2011
/etc/sysconfig/iptables (END)

I don't think your problem is one of redirect, I think it's of the listening service. By default, ssl listens on 443, if you want it 8443. Not sure which Linux flavor you're using, but look for ssl.conf (ie: /etc/httpd/conf.d/ssl.conf).

This will give you a list of currently *listening* services:

netstat -ntap |grep -i listen

In addition to the above
Code:
-A PREROUTING -p tcp -m tcp --dport 443 -j REDIRECT --to-ports 8443
-A PREROUTING -d 127.0.0.1/32 -p tcp -m tcp --dport 443 -j REDIRECT --to-ports 8443
-A PREROUTING -d 10.168.61.237/32 -p tcp -m tcp --dport 443 -j REDIRECT --to-ports 8443
the first rule there makes the next 2 redundant (iptables does first match).
Also, your request is
Quote:
redirect 8443 to 443
but your rules redirect 443 to 8443 (opposite direction ) ... which is it?

Are you really sure you want
Code:
-A OUTPUT -d 10.168.61.237/32 -p tcp -m tcp --dport 443 -j REDIRECT --to-ports 8443
that's for pkts leaving your system to go to another system (usually...)
