Persisting on Source Address

Hello all,

I have the following request from someone in our company:

Got another question for ya…

 

 

Our server side product is setup to listen on port 2000, but when we tried to transfer a file to 10.84.128.173:2000, internally it was going through 10.84.128.162:47512. Since we have to know on the server side where requests are coming from (IP and port), this causes a problem. Is there anyway to force it to go through a certain port?

 

I think what they want is FTP like behavior.(This is a proprietary protocol) So when a machine comes into BigIP on 2000, then they handshake, and decide on a port. I need the transaction from that source to go to the same node there after.

From what I have been able to find it looks like I need an iRule to add to a persistence table. Perhaps

persist SOURCE_ADDR

. I can't seem to get it to work right. I know that it has a mask options, but I don't want a mask because I don't know the mask, just the pool.

Thanks in advance,

Justin
