<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">I have a situation where I need, what I'll call, a high availability router to provide fail over between a cable service, and adsl service, from 2 separate ISPs. There is no requirement for outside access just high uptime requirements for internet access from the lan to the internet. At present I'm looking at just running a perl, or shell, script to ping the gateway and then fail over to the opposite interface, and vice-versa. Anybody know of a better way to do this, or have any experience with a similar situation?<DIV><BR class="khtml-block-placeholder"></DIV><DIV>Thanks,<BR><DIV> <SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 16px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT class="Apple-style-span" size="3"><SPAN class="Apple-style-span" style="font-size: 12px;"><SPAN class="Apple-style-span" style="font-size: 12px; ">Neil Jolly</SPAN></SPAN></FONT></DIV><BR class="Apple-interchange-newline"></SPAN> </DIV><BR></DIV></BODY></HTML>
