If it was just ssh, I would say that maybe permissions were wrong on .ssh
dir or identity file (works best 700/600 respectively).

But since you also have problems with Win ssh client and http for either,
I suspect an mtu path discovery problem. Does anything in the path from
client to server go in through pppoe? If Linux is doing the pppoe, this
should not be a problem. But if some other broadband router is doing
pppoe, you might need to match mtu of the nic on your server with the mtu
of pppoe on the router (ie, mtu 1492 max). I had to match mtu like that
when sending mail directly to an smtp server forwarded to private nic
behind pppoe router.

Note that sshd might depend upon host.allow | hosts.deny settings. What
error do you get from web browsers (or do they endlessly spin)? Can you
telnet to port 80 of server?

I have never had any trouble connecting to OpenSSH in Linux on adsl from
Putty in Windows or Solaris. Although, I do not keep my private keys on
public servers, so Solaris connection was ssh Linux dialup to Solaris, and
then ssh Solaris to Linux using ssh-agent to relay keys. Similarly I
have never had any trouble accessing Linux apache on adsl from Netscape or
wget on Solaris or any Win browsers.
