I have a FWSM set-up in multiple context mode. Management of the FWSM is purely through the admin context. The other contexts have no access (no routes) to the management LANs.
I can get syslog etc from the admin context to my management servers no problem. However I am unable to acheive the same from the other contexts.
From what I can see, this will be due to the other contexts not having access to the management LAN.
Is there anyway I can get the syslog information from the other contexts via the admin context?
I am reluctant to engineer access to the management LAN from the other contexts, as they are on isolated virtual networks with no current access (and no other need for access) at this time.
You have 2 choices really
1) Have the management LAN as a shared vlan between your contexts.
2) Route the syslog messages from the contexts to the management LAN.
It's not clear from your topology how the routing would work.
The advantage of allowing all contexts access to the management LAN is that you are not setting up additional access rules / NAT statements but it comes with the risk of "backdoors" into your managment LAN.
Really need more info on how your topology is laid out, where the management LAN is, does it have a routed interface on the MSFC or is purely connected to your admin context ? But as i say you really only have the above 2 choices.
