Netware 6 w/ SP3; NWFTPD.NLM V5.03.12 2/12/2003. Server has 2
interfaces, on different subnets. I have 2 executions configured, one with
each interface. One interface is internal to a private subnet, it
works OK. The other interface is on the DMZ with a public
address. I can FTP to the server from internal and from the DMZ subnet,
but not from the Internet through BorderManager - connection attempts time
out. I have a Netware 4 FTP doing exactly this, on the same 2
subnets, it works within and from the Internet. I have the same filters
configured, I do a SET TCP IP DEBUG on the firewall, I see it pass packets
in to the FTP server, nothing comes back. From the FTP server console I do
a IPTRACE to the address on the subnet, it finds that address right away.
I do an IPTRACE to the address on the Internet, it times out, gets
nowhere. But I can run NSLOOKUP on this server, it will resolve
internet host names all day long. I have GWIA running on this server, it's
Install warned me it would not be able to resolve, but it does resolve, and
work. Default route for both the 4 FTP and the 6 FTP is the DMZ interface
on the firewall, as it should be. So why can't FTP find it's way back to
the Internet when GWIA can?
