IIS4 with multiple IP's can't connect to ftp server

[JuanSanchez]

I have an NT IIS 4 server with 2 ip's set up with 2 websites.

This is the error message I get.


Error Diagnostic Information
500 'PORT 10,84,120,12210,84,120,123,72,130': command not understood

The first IP is 10.84.120.122 the second IP is 10.84.120.123
in the error you can see how they both are concatenated.

When ever I try to pull a listing from my FTP server it returns this error. The FTP is on a different machine NT with IIS 4.
Any Idea's

no reverse dns setup for the non routable ip's probably...
