[doc] Issue in "Configuration"

[lpinne]

Hi,
in the "Operation system Security Hardening Guide for SAP HANA for SUSE Linux Enterprise server 15 SP2 and later"
the section "2.4 Configuration" (
https://documentation.suse.com/sbp/sap-15/html/OS_Security_Hardening_Guide_for_SAP_HANA_SLES15_SP2_and_later/index.html#id-configuration )
the link "Configuring HANA firewall" ( https://www.suse.com/documentation/sles-for-sap-15/singlehtml/book_s4s/book_s4s.html#sec.s4s.configure.firewall-hana ) is broken.

Regards,
Lars
