rfoulk,
I'am suprised to hear, that you can run the JTWS from behind a firewall and using NAT.
I have tried it several times and it doesn't work on my office PC ( network, proxyserver, IE 5.0 , Win NT ) although the java runtime interface was installed correctly and works.
With JTWS, I can enter my username and password, but any attempts to logon fail.
"NoRoute to Host Exception" Error messages all the time.
JTWS is not able to establish the "dedicated" connection required.
BTW, I wasn't even able to use the old TWS on this office PC. Frustrating !
On my home PC, I have no problems at all with JTWS or TWS 3.0 both versions just work fine.
I can access my datek account at any time , from office, from home, via their website or through QuoteTracker-software - it doesn't matter. It always works.
I don't know what kind of problems IB has with enabling customers to access their accounts from behind a firewall or through a network but they say it has to do with security issues - same reason why my admin won't touch the firewall and internet-settings.
