SSl VPN

Hi Vanja,

Thank you for reaching out to Sophos Community.

To upgrade from v18.5 to V19.5 MR3, kindly see the changes you must change below. Also, there are no changes to certificates.

 Sophos Firewall: SSL VPN "IPv4 lease range" changes OR global settings update gives error "You must enter a network IP address." in SFOS v19. 

Please see the release not for the upgrade path 

https://docs.sophos.com/releasenotes/index.html?productGroupID=nsg&productID=xg&versionID=19.0

Hi Erick,

Is it possible to directly update  from v18.5 to V19.5 MR3 ?

regards

Hi Vanja,

Unfortunately no, you need to upgrade first to V19.0. 

You may double-check with the release note for more information or see below. 

OK. Thanks. Is it , by your experience, to update to from 18.05 straight to  20.0. ? The Sophos release notes say yes. What is Your advice?

Hi Vanja,

Upon verification, going straight to v20.0 is all good. However, remember to do a backup.

Note: After you upgrade from 18.5 versions to 19.x.x, traffic may not flow through your remote access SSL VPN connections if you've added a custom host (for example, IP address range, list, or network for the leased IP addresses) to the corresponding firewall rule.
