i have a strange packet filter behaviour, maybe you can help me.
I'm trying to use my directly connected LDAP-server (ssl, port 636) for user-authentication in Astaro, but astaro always filters the packets.
ASG: 192.168.1.1
LDAP: 192:168.1.2
Rule #1:
Source:
192.168.0.0/24
192.168.1.0/24
192.168.2.0/24
Destination:
192.168.1.2/32
etc.
Service:
ICMP, 443, 53(tcp/udp), 636 etc.
Logfile:
19:52:20 Default DROP TCP 192.168.1.1 : 42467 → 192.168.1.2 : 636 [SYN] len=60 ttl=64 tos=0x00 srcmac=00:30:18:aa:aa:aa dstmac=00:00:00:00:00:00
19:52:22 Default DROP TCP 192.168.1.1 : 42467 → 192.168.1.2 : 636 [SYN] len=60 ttl=64 tos=0x00 srcmac=00:30:18:aa:aa:aa dstmac=00:00:00:00:00:00
With a dedicated rule with the firewall-interface 192.168.1.1 as source it is working, but not with 192.168.1.0/24. WHY?
