Hi MY network setup
ISP terminated in router ---> ASA5510--L3(3560)-L2 -LAN
Syslog needs to received from router to local machine,
I have added the route in router, and excluding NAT in ASA. From local machine i am able reach router , but from router unable to reach local machine (or syslog server)
Relative information is required if you want help. Here's an example.
access-list SYSLOG_SERVER extended permit ip host 10.10.20.17 host [router IP]
static (inside,outside) 10.10.20.17 access-list SYSLOG_SERVER tcp 65535 10000
access-list outside_access_in extended permit udp host [router IP] host 10.10.20.17 eq syslog
In the router you will need a static route to the inside host pointing to your ASA.
ip route 10.10.20.17 255.255.255.255 [ASA public IP]
