You have some control on the outbound ports on the Linksys routers but nowhere near what you can get with iptables. If you want to, for example, restrict outbound port 80 to www.microsoft.com, it's much harder to do at the Linksys level, if it's even possible. > > Personally, I use a Linksys router/firewall with some predetermined > > ports forwarded to my Linux system (none to my Windows systems) and add > > tcpwrappers to restrict which hosts are actually allowed to use that > > service.

Not all of your computers are behind > the linksys firewall and that is the problem!!!!! I have my systems behind the Linksys firewall but it forwards a few ports to my server. It's how mail and ssh get in and how I can serve up web pages to the outside world. -- Ed Wilts, RHCE Mounds View, MN, USA mailto:ewilts@xxxxxxxxxx Member #1, Red Hat Community Ambassador Program -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
