  • hope  v20.0.2 MR-2 will get release soon. also kindly inform to your developer team that atleast  v20.0.2 MR-2 will not create any issue to update firmware to firewall. as version SFOS 20.0.0 GA-Build222 cause issue for update due to DHCP and to get update this firmware we have to disable the DHCP in firewall.

    if possible can you provide any approx. date for the release of  v20.0.2 MR-2 firmware.
