Hello there,
in the meantime i got nearly everything working with my CCR2004. I have two hosts that are directly connected to the router (Synology NAS on bond 2, and an Intel NUC on sfp-sfpplus11, each with 1Gbit/s connected). All other hosts are connected via old Cisco SG300-10 Switches, also running with 1Gbit/s.
Everything is working except this two mentioned hosts. I can’t reach them and the Synology also won’t get a DHCP lease. When I connect them directly to my PC everything works fine. All other hosts are working perfect.
When I check the MAC Addresstable, only the Synology is visble, tested both interfaces, but only one is connected:
/interface bridge host print
Flags: X - disabled, I - invalid, D - dynamic, L - local, E - external
# MAC-ADDRESS VID ON-INTERFACE BRIDGE AGE
0 D 00:11:32:0A:3D:15 bond2 bridge1 26s
1 D 00:11:32:0A:3D:16 bond2 bridge1 29s
[SNIP]
16 DL 48:8F:5A:1A:43:30 bond2 bridge1
[SNIP]
19 DL 48:8F:5A:1A:43:38 sfp-sfpplus11 bridge1
In the firewall log is also a strange entry for the Synology:
input: in:bridge1 out:(unknown 0), src-mac 00:11:32:0a:3d:15, proto UDP, 0.0.0.0:68->255.255.255.255:67, len 328
Hardware:
- CCR2004 with S+RJ10 SFP
- Synology DS1511+ (will be replaced soon)
- Intel NUC
- CAT6 or better ethernet cables
In the attachement you’ll find my configuration export.
What am I missing? Do I have to set something special on the interfaces for this two hosts? Please help a Mikrotik rookie who already loves his CCR2004 and don’t want to use another switch for this two hosts 
.
Kind regards
