Hello; I am running syslog-NG on a server inside of a DMZ, and on that server I'd like to just forward all messages into my internal syslog-NG server. I feel this is better than having to create a new firewall rule for each new DMZ node. I have a simple syslog-NG config that looks like this: ---------START syslog-ng.conf----------- @version:3.5 @include "scl.conf" @include "/etc/syslog-ng/conf.d/*.conf" options { time-reap(30); mark-freq(10); keep-hostname(yes); chain_hostnames (off); flush_lines (0); time_reopen (10); log_fifo_size (1000); use_dns (yes); use_fqdn (no); create_dirs (no); }; source s_relay { udp(ip(0.0.0.0) port(514) so_rcvbuf(425984)); tcp(ip(0.0.0.0) port(514) max-connections(250) so_rcvbuf(425984) log_iw_size(25000) so_keepalive(yes) log_fetch_limit(100)); syslog(ip(0.0.0.0) transport("tcp") port(1514) max-connections(500) log_iw_size(25000) flags("threaded") log_fetch_limit(100)); }; destination d_syslog_tcp { syslog("10.5.5.10" transport("tcp") port(514)); }; log { source(s_relay); destination(d_syslog_tcp); }; ----------END syslog-NG.conf------------- The problem that I am experiencing is that my messages, once received by my internal syslog-NG server, look like the following: Apr 26 17:31:06 relay-sng-server 126 <30>1 2017-04-26T17:32:01-04:00 relay-client-host-X appserv - - - 606881792 140565409392384 INFO: @2 SessionExchange::ProcessTCPRead Apr 26 17:31:06 relay-sng-server 124 <30>1 2017-04-26T17:32:01-04:00 relay-client-host-X appserv - - - 606881792 140565409392384 DEBUG: OpenSSLHandler::PerformHandshake I am hoping not to muck around too much with my config for my internal syslog-NG servers, and want for the messages above to appear as coming from relay-client-host-X and NOT relay-sng-server. It could potentially be nice to know that the message was first received by relay-sng-server, but... I was considering opening another TCP port on my internal syslog servers, and using that to send from DMZ, then a rewrite, but that all seems far more complicated than necessary. Am I missing something on my syslog-NG conf? Any suggestions greatly appreciated! Thanks all in advance, -Vadim
