Hello,
 following the:
 - config

 - outputs

Config:
    @version: 3.26

    source s_net1 {
      udp(
        port(8001)
        flags(no-parse)
      );
    };

    destination d_file1 {
      file("/tmp/prefix-first-second-suffix.log"
        template("$1 - $2 - $3 - $4\n")
      );
    };

    destination d_file2 {
      file("/tmp/prefix-second-first-suffix.log"
        template("$1 - $3 - $2 - $4\n")
      );
    };

    rewrite r_rule {
      subst("([a-z]+)-([a-z]+)-([a-z]+)-([a-z]+)", "", value("MSG"), flags(store-matches));
    };

    log {
      source(s_net1);
      rewrite(r_rule);
      destination(d_file1);
      destination(d_file2);
    };

Message:
    echo "hello-foo-bar-world" > /dev/udp/127.0.0.1/8001
    echo hello-i-j-world > /dev/udp/127.0.0.1/8001

Output:
    szemere at tp:/tmp$ cat prefix-first-second-suffix.log
    hello - foo - bar - world
    hello - i - j - world

    szemere at tp:/tmp$ cat prefix-second-first-suffix.log
    hello - bar - foo - world
    hello - j - i - world

Hello William,
 What you are looking for is the "store-matches" flag of the regular expressions. https://nam05.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.syslog-ng.com%2Ftechnical-documents%2Fdoc%2Fsyslog-ng-open-source-edition%2F3.25%2Fadministration-guide%2F68%23TOPIC-1374104&data=02%7C01%7Claszlo.szemere%40oneidentity.com%7Cfba08320ff2d45ad333e08d7d1c557e6%7C91c369b51c9e439c989c1867ec606603%7C0%7C0%7C637208517827005664&sdata=TvYjtacvhyn%2F1HVUopa7zmS98DoD065LvnerpRZGrtg%3D&reserved=0

 You can "store" the matching part of a subst rewrite rule. Which can be later used in a template function, on the destination site. So you can "reassemble" your log message in any form you want.

Hello everyone,

Is it possible to change a position of an information within the message?

From: 2020-03-26; 17: 55: 22; RTCGNMGA0101: RT_SRC_NAT_PBA_ALLOC :; 100.64.1.114:38784-38847; 177.51.112.218;

TO:
2020-03-26; 17: 55: 22; RTCGNMGA0101: RT_SRC_NAT_PBA_ALLOC:; 100.64.1.114; 177.51.112.218:38784-38847;

Basically, I would like to change the position of the connection port within the message.

How to do this?

TKS
