Title: MultiWAN and FTP
Post by: namezero111111 on April 19, 2018, 05:12:00 pm
Dear folks,

given a MultiWAN setup with Gateway group load balancing, there appears to be an issue with outgoing FTP where:

1. The control connection (21) is opened over GW1
2. The data connection is opened over GW2

In that case, listing the directory in passive mode fails.

Is the os-ft-proxy plugin able to handle this issue or is there a more elegant way short of configuring static data ports for FTP and forcing them into a failover group?

Thanks in advance!

Did you fix FTP with multiwan?

FTP Proxy wont fix this since this would be a local initianted connection

maxxer, we setup two failover pools for subranges so that they get bound to one gateway.

Alternatively, you could try sticky connections, but that causes other issues for us relating to stalled connections (2376).

You could try sticky connections combined with state killing after failover?

State killing shouldn't be necessary; states will be flushed anyway when the gateway goes down.
