I have a Linksys WRT54GS router networking 2 PCs. Everything works fine with this setup including Earthlink email (POP3). But when I enabled the router's Parental Controls, I cannot send emails. It says it is trying to send. but never accesses the server. Parental Controls has a setting to limit email capability but I have this set to full access. If I disable Parental Controls, everything works fine again. Linksys support has been no help to date.
