(feature) Bind SocketInitiator to specific host/port

[cyphersys]

Hello!

I found that QuickFix/J has settings on Initiator section as SocketLocalHost and SocketLocalPort to bind the socket initiator to a single IP and/or Port. Is possible implement them?

Thank you in advance

In QuickFix/n you also can set direct ip and port in *.cfg or replace in init Session setting code this params:
SocketConnectHost - your direct IP
SocketConnectPort - port
SSLServerName - DNS name for SSL connection

Hello,

Thanks for your reply. I was specifically referring to binding SocketInitiator to a single IP (interface) in case the computer where QF/n Initiator is running has multiple IPs assigned to it.

Currently QuickFix/n selects the first IP address of the NIC.

Thanks!

Sorry, I misunderstood you at first. Your idea is cool, especially if there are restrictions on rate limits for IP. Now they don’t have such support out of the box, but you can add

socket.Bind(new IPEndPoint(settings.LocalIp, settings.LocalPort)); 

after

quickfixn/QuickFIXn/Transport/StreamFactory.cs

Line 81 in 63c2e05

socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

also you need to add you custom local interface fields(LocalIp, LocalPort) to SocketSettings. Currently i can't check it, but hope this works.

Hello, sorry for my delayed reply.

I have done something very similar to your suggestion, previously before writing this issue.
I only wanted to request it as a native feature of QF/n.

Thank you

This is a feature request that I'm never going to find time to work on. I'm going to close this issue.

I would be happy to see someone contribute this feature, though.
