Logging framework |
If your device is using a configuration previously restored from a Cyberoam backup, and you haven't regenerated the appliance certificate on SFOS, upgrading to 19.0 results in the appliance operating in fail-safe mode.
The appliance certificate generated on Cyberoam devices uses a weak signature algorithm (MD5). SFOS 19.0 doesn't support appliance certificates with this algorithm.
How to verify before upgrading:
To verify the signature algorithm of the appliance certificate, run the following command on Advanced shell:
openssl x509 -in /conf/certificate/ApplianceCertificate.pem -text -noout
Do not upgrade to 19.0 if the output shows the signature algorithm md5WithRSAEncryption.
|
You must regenerate the appliance certificate.
See Appliance goes into fail-safe mode when firmware upgrades to 19.0 GA.
|
| NC-94354 |
Web |
Upgrading to 19.0 results in a factory reset. If you've changed SSL/TLS inspection's log retention period from the default value (1 month), upgrading to SFOS 19.0 resets the device to the factory configuration. |
Do as follows:
- To see the Log retention period, go to Reports > Show report settings > Data management and see Retain SSL/TLS inspection logs of the past. It's the last option on the list.
- Change Retain SSL/TLS inspection logs of the past to 1 month.
- Upgrade to 19.0.
- Change the setting back to the previous selection if you want.
The firewall deletes logs beyond the specified period at midnight. To retain the logs based on your previous selection, revert to your selection before midnight.
See Upgrade to 19.0 GA results in factory reset.

Upgrading from 18.0.MR6 to 18.5.MR1 results in a factory reset. |

| NC-82331 |
Security Heartbeat |
From 18.5 MR2, Sophos Firewall encrypts certificate keys. So, when you upgrade to this version, the firewall refreshes the certificate used by synchronized endpoints to send a Security Heartbeat.
If DNS resolution to sophos.com fails, the endpoints may not get the new certificate from Sophos Central, and the heartbeat fails.
|
Do as follows:
-
Make sure the endpoints have network connectivity during the upgrade. They can then fetch the new certificate from Sophos Central.
- If the endpoints are blocked from getting DNS resolution for sophos.com to download the new certificate, go to the corresponding firewall rule and temporarily clear the checkbox "Block clients with no heartbeat".

Email logs for bounced emails may show IP addresses that aren't configured as the source address.
Log entries are generated for connection table entries rather than from routing. For conntrack creation, the firewall uses any gateway IP address as the original source address (example: Port4: 10.24.255.254). When routing is done on layer 3, the decision may be to route that connection through Port2, but the original source isn't changed.

When LAN users want to access a web server deployed in the LAN zone and protected by a WAF rule, these requests don't work. Requests from the LAN zone reach the web server directly without passing the firewall. |
WAF rules control traffic for sites hosted on the WAN interface. For internal servers, configure the DNS server to resolve the domain to the backend server directly.
Alternatively, to host the site in the LAN zone through WAF, you need a second WAF rule that listens on the internal interface with a different, internal-only domain.

When system route_precedence is configured to give VPN routes higher priority than static routes, the firewall doesn't send the traffic through the IPsec tunnel. Instead, it routes the traffic through a matching static route. This occurs if a static or local route exists, directing the traffic to a non-WAN zone. The route precedence command only applies to traffic destined for the WAN zone.

In transparent mode, Citrix clients aren't aware that there's an HTTP or HTTPS proxy in the middle. So, they start using a proprietary protocol (not HTTP or HTTPS) using the HTTP and HTTPS ports. The proxy doesn't understand this and waits for a client request while the Citrix client waits for the server to respond. So, launching a .ica file with Citrix web or application fails.

You need to punch a hole in the firewall. Do as follows:
For traffic from the LAN zone to the destination IP addresses of your URL in the WAN zone to launch the .ica file, create a LAN to WAN firewall rule with web policy set to None.
