Question about Cyberguard SG300 (00852503000366) Firewall
Cyberguard sg300 drops tunnel out and requires a power cycle to reconnect. (It stops at negotiating stage 1 after dropout)
Settings are aggressive mode, preshared secret, dead peer detection, but no compression.
Initiate stage 1,2 rekeying also set.
Firmware levels are all the same, v3.1.5u4
If you've got locked out of your CyberGuard / SnapGear firewall, as long as you still have SSH access you can regain access without doing a factory reset.
From the command prompt type "enableweb"
The web interface has been enabled on ALL interfaces, for HTTP and HTTPS.
Please ensure you review the administration access control options.
As it says, this will re-enable access on ALL interfaces, including Internet, so you need to review the choices, FAST! --------- keep updated.thanks.

This seems like a a common problem for many who are using an SG300 (though I believe that other SG series are affected) for a few months on TPG ADSL2+.and ADSL+2 modems. It took too long to connect to the DSLAM, sometimes several hours. I
tried different modems in front of this router etc but all to no avail.
Different configs etc, but nothing worked. I'd simply have to leave the
router to connect of it's own accord. It'd continually try and fail
over and over until it connected. Once connected though it was always
I thought that I had the latest firmware as I only updated it about two months ago. Anyway the latest firmware from Cyberguard/Snapgear rectifies this problem in particular. It seems to be isolated only to TPG ADSL2+ in combination with the SG series firewalls. Get firmware version 3.1.4u2 if you're having issues with SG series firewalls connecting to TPG ADSL2+.......This might solve this problem....sodeep

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.
