Re: trading partner security


Jim,

Just say NO !!

Best answer is a separate box under your control, Maybe a small Linux or FReeBSD OS and 486 processor that sit's in your DMZ and pulls the file from the iSeries and with a Secure Shell Copy or NFS, or FTP with some Exit program protections , and then makes it available to the customer via FTP from their range. You could further secure the box with IPFW2 or IPTables on the FTP Server.

        Good Luck,
        JMS..

is adamently refusing to specify a single ip they are coming from,
saying that is a security risk to them, and has given us 3
ranges totalling over 700 addresses. I don't have a problem
but our firewall person is freaked and refuses. I assume they
have a herd of routers and servers in their farm.
note: partner is defense related. 400 has decent ftp exit control.
should i worry?
