At present, the Check Point Infinity Portal enforces an 8 character limit for the TLD portion of an added domain. The maximum TLD length specified by RFC 1034 is 63 octets and many modern, valid TLDs, such as .engineering, exceed this set character limit.
This issue is ticketed and confirmed by support, but hoping some additional visibility here can be helpful for escalation within Check Point. We're migrating a client from Avanan to Infinity and this limitation is preventing the use of their domain. Avanan does not have this limitation.
