cannot connect to ssl site with PPPOE (dsl connection)

I cannot connect to an https site using my existing sbc (ppoe) dsl connected to a linksys wireless router.  I tried the router on a comcast (cable modem) connection and it works fine.  I just cant seem to get it to work with with PPPoE connection.  

Do you think its a problem with the router configuration or could it be the configuration of the secure site?

The configuration of the secure site doesn't know if you're connecting with PPPoE or via cable, so it must be a configuration problem with your router.
In order to "debug" the problem from your PC,
try: "C:\>telnet <hostname> 443"
You'll see if you can connect to the server (you'll see the screen will go blank), or if the server is unreachable ("Connect Failed", but after a rather long time), or if the server rejected your attempt ("Connect Failed", but after a short period of time).

What kind of router? DSL with PPPoE has a few extra bytes of packet overhead, add SSL encryption to that, and you may be bumping into a MTU size issue. If your router supports it, change the MTU size to 1492 to prevent packet fragmentation

MTU size is 1492.  The router Im using is a linksys wireless router 802.11B.  I've seen this problem with a netgear router as well.  We are both using SBC PPPoE connection.  

I will try the telnet to see what the root of the problem is.

thanks,

Nick
