If it works on the LAN but it is not working through the firewall,
possibly the firewall?
I am not big on all network/cisco stuff, and my experience on this was
not related to BQ/Nuonce, but I had to request that the PIX 'fixup' be
turned off for outbound sessions. I think this is what it is called? It
is where the PIX will read into sessions to mask the identity of all
services, like "220 ESMTP Sendmail" being replaced by *** *****
********.
This was for an outbound SMTP issue (Exchange) as all mail was not
sending because of it, but where 'fixup' is still working just fine when
left turned-on for the inbound sessions. I think this was related to a
recent update to the PIX software, so I wish I knew more here... Another
weird thing, it was only Exchange, as I had a sendmail server behind the
same PIX that was sending just fine.

Subject: [coba-e:08183] TCP Checksum Invalid
Hello!
I recently installed Nu-CentOS-BQ-4.6.iso on a Dell C521 computer.
On the LAN, it seems to work fine, but outside viewers cannot see it. I
enabled ports 444 and 81 as well as the normal HTTP, HTTPS, DNS, POP,
IMAP, SMTP and FTP through the firewall, which is Cisco PIX506E.
I installed Ethereal on a system on the LAN and accessed the server's
admin interface. Many of the TCP packets from the server showed "TCP
checksum invalid" errors, which I assume is why the packets are not
making it though the firewall.
Is this a known issue with the 4.6 release? Has anyone else experienced
this?
