Using Synology for a while but really a novice. Trying to optimize my system.
Have my DS1019 setup with static IP & 2 LAN connections to Unifi Dream machine.
Watched older video SMB Multichannel vs Link Aggregation - what should you use?
Went to setup Dynamic Link Aggregation with hopes of having faster data transfer as want to start using remote access.
But looks like this only works with DHCP server settings.
This is just a home network so I won’t have issue with multiple simultaneous users access it.
You can’t create 2Gb/s from two 1 Gb/s connections, However you can have two parallel 1 Gb/s simultaneous connections from two devices (each at 1 Gb/s). OK?
To answer your question directly - yes you absolutely can use a static IP with Link Aggregation. The bonded interface just looks like a single NIC to DSM, so you configure your static IP on that bond interface the same as you normally would. What you won’t have is TWO separate static IPs for the two ports - they merge into one logical interface.
That said I’d gently push back on the goal here. Link aggregation for remote access won’t actually give you faster speeds. The bottleneck for remote access is your ISP uplink, not your LAN. Whether your Synology is doing 1Gbps or 2Gbps internally doesn’t matter when data has to travel through your internet connection.
What Dynamic Link Aggregation (LACP) actually gives you is redundancy (one link fails, the other keeps going), and higher aggregate throughput when MULTIPLE clients hit the NAS simultaneously. For a home setup with one user at a time you won’t see any benefit.
For your single-user scenario SMB Multichannel would serve you much better if faster LAN transfers is the goal - it can aggregate multiple paths between a single client and the NAS. And for remote access specifically the improvement comes from your WAN setup, not LAN bonding. Tailscale is worth a look if you haven’t tried it - rock solid for home NAS remote access.
