Cyberguard Computers & Internet - Recent Questions, Troubleshooting & Support
I made a change in the firewall and now have
Hi,
yes that device uses a protocol called SSH which is a command line based interface.
from a windows machine I would recommend using "Putty" as an SSH program to work with(make sure to select SSH as the default is telnet under the host name which will be its IP in this case).
once you connect to the device and sign in you can type"enableweb"
and it will reset all ithe interfaces to allow webaccess again.
other than that a hard reset would work as well.

hope this helps

I'm getting an error message
This means that it is detecting the Operating system of the queried host wrong and I would simply ignore the error or turn detection off entirely. While it determines the operating system of the queried
host by looking in detail at the network characteristics
of the HTTP reply received from the web site.
The reported operating system may be different to the one you expected
because of any number of reasons that make it unreliable. For example:
-
The site could be using a web proxy cache, such as
Novell BorderManager
FastCache,
Inktomi
Traffic Server
or a server running the open source
Squid
software.
In this situation we will be connecting to the reverse web proxy
rather than the originating web server,
so will detect the cache's O/S rather than the web server's.
Some proxy caching systems add headers to web server responses, such
as the standard "Via" header. If the "Via" or "X-Cache" headers are
found we report that the site is proxied.
-
The site could have a server load balancing device (SLB) like
Cisco
Web NS,
Resonate Central
Dispatch or
BIG/ip.
Some of these SLBs handle the TCP connection themselves,
so we detect the SLB's operating system.
Others use TCP/IP packet level Network Address Translation techniques,
where we detect the operating system of one of the back-end web servers.
-
The site could be using a TCP connection-level proxy firewall,
such as provided in the
TIS Gauntlet,
BorderWare,
Raptor,
CyberGuard or
IBM SecureWay
firewalls,
or some other kind of HTTP level proxy.
In these cases we will receive data from the intermediate machine rather
than the web server, so detect the intermediate machine's operating
system.
-
They could load shares across multiple servers using different operating
systems
with round robin DNS.
In such cases each query might detect a different operating system.
-
They could have just changed the default configuration of their TCP/IP stack,
perhaps for performance reasons,
or have an unusual LAN environment.
- Or something new has just come out and you have an older firmware revision that doesn't recognize newer packet standards.
Cyberguard sg300 drops tunnel out wont restart
Hi
Thanks for using FixYa. These are the main causes due towhich drops tunnel out and need a power cycle to reconnect. Please make sure thatthe Cyber Guard SG appliance has a default gateway by configuring the Internetconnection on the Connect to Internet page or assigning a default gateway onthe IP Configuration page. Ensure that the tunnel settings for the Cyber GuardSG appliance and the remote party are configured correctly. Also ensure thatboth have IP Sec enabled and have Internet IP addresses. Check that the CA hassigned the certificates. The remote party has gone down. The remote party hasdisabled IP Sec. The remote party has disabled the tunnel. The tunnel on theCyber Guard SG appliance has been configured not to re key the tunnel. Theremote party is not re keying correctly with the Cyber Guard SG appliance. Forfurther reference see the link---

I can get a computer on the LAN but not the WAN
The WAN (Wide Area Network) port is used for access to the internet through the use of a DSL or Cable modem.
You can't connect a pc to the WAN port it must be connected to one of the LAN ports.
Cable modem connection keeps repeating checking
I had a similar problem a while back when I bought a new cable modem. I didn't realise that my cable provider needed to have the serial number of my cable modem configured on their system.
I ended up calling them to ask them about the problem.
There is no way I could have solved it without calling them.
I think it is to do with stopping unauthorised users from connecting to the cable.
I remember they wanted my name, age and grandma's inside leg measurement before they would help me.
So if you have nothing to hide just give them a ring and make them help you. This is what you pay them for after all.

Help with a unblock code
ok, on the internet window, click on tools, then internet options, then go to the ADVANCED tab, and click on the reset buttons and hopefully this fixes ur issue and if it does dont forget to rate me as FIX YA
Blocking email
The ISP provider changed our IP address when we reset the modem.(even though they swear it was a fixed IP) The mailguard delivery address is fixed so the redirected mail from mailgaurd no longer had a valid address for delivery.
You can fix this by correcting the mailguard delivery IP address (phone them in business hours) or by providing Mailguard with a name address instead of an IP address .
Simple but frustrating until you think of checking to see if the IP addresses of your server and mailguard match
How to connect my MSSQL server through VPN by using PPTP
192.168.1.X is a local ip address ,, i trust that thhe vpn is in seperate places and is done with the wan ip over an internet connection?????
OK maybe the problem isnt on your side but the main office building,, when connecting , have someone looked for repeated attemps to connect by observing the fire wall,, if it appears to be blocked byu the firewall simply diasable any and try it out.. If it works then all you need to do is set the firewall correctly..
I was reading the ip address in your original post and those are local address,s are you certin the VPN is correct ???? did you use the correct STATIC IP ADDRESS ASSIGNED BY YOUR ISP??

thank you...
Cyberguard SG300
From the main configuration screen select Network Setup, and then click on the Connections Tab. In the tabline below that click on Aliases.
At this point you input the Alias IP address and the netmask and add it, selecting port 25. The firewall now knows that it is to forward all traffic on port 25 to the computer that has the IP address you put in.
You should be aware that doing the above opens a direct access point into your network! Port 25 is the port used for SMTP (Sendmail) and it is the most vulnerable and most hacked service on the Internet! You should seriously consider not doing this.
A better option would be to goto the DMZ tab and configure a DMZ net on your firewall - you will need to obtain a second routable IP address from your ISP to do this though. By creating the DMZ and then routing port 25 to a machine inside the DMZ you isolate the machine running SMTP from all of the other machines inside your protected network and so make a compromise much less likely.
All of the systems inside your protected network will still have demand access to the machine in our DMZ, but the machine in your DMZ would be unable to initialize access to the protected network, which is a much safer setup.
Port 25
Which Firewall?
Model and make please
