Syslog Traffic Generating issue

RouterOS General
1

Hi Gurus,

First Check my configuration

WAN 125.16.XX.XX/30
LAN 10.10.10.1/28
LAN 10.10.11.1/28
LAN 10.10.12.1/28
LAN 202.XX.XX.33/27 (public Ip’s)
LAN 202.XX.XX.34/27 (public Ip’s)
LAN 202.XX.XX.35/27
LAN 202.XX.XX.36/27

Here i have only one ip in WAN interface but i have 32 public ip’s in LAN side some customers are using public ips and some ip’s are used for netmap like 10.10.10.0/28 netmap to 202.XX.XX.35, 10.10.11.0/28 netmap to XX.XX.36 , works good and fine. i routed LAN syslog traffic to Syslog server but here shows only WAN interface ip (125.16.XX.XX) but i need log for Individual ip like what i netmap ( 202.XX.XX.35,36,34) how can it possible. Sorry for the poor english.

Thanks & Regards

is your Syslog server behind WAN?.. you need to disable NAT for Syslog packets, so src-address will not be rewritten with WAN’s IP

p.s. ‘netmap’ to /32 address is just ‘src-nat’ to the same address - just FYI

Hi ,

Syslog Server in WAN Side , src-Address Ip’s are netmapped with Public Ip’s . but not getting log traffic with Multiple ip’s.

so, the device sending info to syslog sees necessary ip at http://ipadd.com, but shows different ip for syslog server?..
