The assumptions I'd make about your situation are:
- You're connecting with IP
- You're ISP is bringing you up outside the firewall (CDMA data, CDPD or
such)
- A firewall exists that protects the server you're trying to access
Are those right?
Today I believe the main option you have is to dial-in behind the firewall
(if that is possible). Most corporate-run dial-in pools are behind the
firewall. Some wireless data services support this (GSM and CDMA data).
The other technologies commonly used are:
- PPTP
- L2TP
- SSH
- IPSec
The only one I know if running on the Palm is SSH and that's only in a
telnet app (TopGun Telnet I think). In the long term I hope we get to
IPSec. It's what all the major firewall vendors (including Cisco and
Microsoft) are touting as the standard and it's also a very general and
efficient technology. I believe there's some performance issues with IPSec
but I also believe they are solvable with enough cleverness.
I'd be interested in others thoughts!
One worry I have is that PPTP is to heavy to for Palm devices now, but it's
widespread use is going to delay IS departments rolling out IPSec.
