CISCO ASA blocking own syslog messages from sending back across VPN


I have a ASA device at a remote site with a management interface with IP address

and also on this interface are switches that also have ipaddress on the 192.168.1.x range.

It is connected back to the main site via a site to site VPN.

The rules on the firewall say that any traffic comming in to firewall on the subnet to ip address should be sent back across a site to site vpn.

Now for the switches that are using the ASA as there default gateway this all works fine, however the traffic from the ASA its self fails and is blocked be the policy on the interface. (however the interface only has the default rule, traffic allowed to any less secure interface)

doing a trace, traffic from the switch never hit this interface rule they just get routed to the internet and then hit the VPN.

How is traffic from the firewall its self treated different and does hit this rule and is blocked. how do i insure it goes across the VPN and is not blocked.

See if you allow packets reversing/leaving returning over ....I.e leaving one interface to then come back on itself.
Same-security-traffic permit inter-interface or intra-interface will allow packets leaving the to go through the vpn

It this the actual Management interface, M0/0 for example, or is it just the inside/LAN IP of the firewall?

If its just the inside IP add the following

management-access inside

Then try again
