"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob

Hi. My client is trying to set up a more thorough firewall on his server and it seems like connecting to IQFeed keeps getting in the way. Whenever we tighten the screws, it seems like the IQFeed connection doesn't work and we have to back off.

Is there some general information on the ports that IQFeed uses, and the servers the ports should be allowed to access? (I'm far from an expert in this topic -- so let me know if that question even made sense!)

Thanks in advance for your help!

jlarmee, this is going to be dependant upon what exactly you are needing to function. The various types of data in IQFeed are transmitted over different ports to the client.

We have 2 server farms currently which are commonly referred to as the "148" server farm and the "156" server farm. Each farm is identical in IPs and ports and customers are load balanced between them so you might need duplicate firewall rules setup to allow for connections to each server farm. Each server farm operates on two separate port ranges as well that are copied and 55000 apart from each other (one in the 5000 range and the other in the 60000 range). Keep in mind also that ALL connections for IQFeed originate from the client application so no port forwarding should be needed.

The preferred method is to open the entire subnet on the following port ranges.
66.112.156.XXX ports 5000 - 5050 and 60000 - 60050
66.112.148.XXX ports 5000 - 5050 and 60000 - 60050

The reason for this is that IP addresses and port numbers change on occasion (adding or subtracting servers). This will allow you optimal use of the feed while having very little potential to having to revisit firewall configuration at a later time.

If you need a more detailed (or "tighter security") model, the following information can be used but keep in mind that we do modify these ports occasionally for various reasons so it is entirely possible these will change and cause feature(s) of the feed to no longer work.

The "156" server farm.
66.112.156.210 - 66.112.156.214 ports 5000, 5001, 5005, 5009, 5014, 5015, 5018, 5020, 5050, 60000, 60001, 60005, 60009, 60014, 60015, 60018, 60020, 60050
66.112.156.220 - 66.112.156.229 ports 5002, 5003, 5004, 5013, 60002, 60003, 60004, 60013
66.112.156.110 - 66.112.156.119 ports 5002, 5003, 5004, 5013, 60002, 60003, 60004, 60013

The "148" server farm is exactly the same except the ip addresses.
66.112.148.210 - 66.112.148.214 ports 5000, 5001, 5005, 5009, 5014, 5015, 5018, 5020, 5050, 60000, 60001, 60005, 60009, 60014, 60015, 60018, 60020, 60050
66.112.148.220 - 66.112.148.229 ports 5002, 5003, 5004, 5014, 60002, 60003, 60004, 60014
66.112.148.110 - 66.112.148.119 ports 5002, 5003, 5004, 5014, 60002, 60003, 60004, 60014

Thanks!

This very helpful!. I think the entire subnet and port range should do it. We shouldn't need to get to the detailed list. I'll keep that under my hat.

Yes, this still the way our server farms are setup.
