From 31875d4970baa02e08b719fdfea6f43e9e2f7e77 Mon Sep 17 00:00:00 2001 From: Julian Anastasov Date: Thu, 24 May 2018 23:40:12 +0300 Subject: ipvs: register conntrack hooks for ftp ip_vs_ftp requires conntrack modules for mangling of FTP command responses in passive mode. Make sure the conntrack hooks are registered when real servers use NAT method in FTP virtual service. The hooks will be registered while the service is present.
