I live in CA outside of someplace where I can obtain centrex ISDN. Therefore I must watch my metering minutes. As my telnet sessions are often longlived, they get passed over a permanent v.34 line; ISDN is used in the evenings and simply set as a default route for those hours and then dropped. What I'd like to do is redirect all outgoing requests to WWW servers to go out the isdn line. Ie: rdr 0.0.0.0:80 -> tun1. I've thought of a number of ways to do this; all are horrible hacks. * use ipfw to divert packets to :80, use custom hack (or nc) at the divert port to readdress and source route out. * hack my proxy server to source route. * have an external proxy server with a static route through the proper interface. * build a custom route for each www access through the proper interface. * dedicate a seperate machine as a proxy server internally with a default route out. It appears that my isp's disallow source routing however. Building routes one way or another appears the only viable method. Or is it? Have I missed something? -j
