PIX problem when it configured with syslog server with tcp port
Did someone ever encounter PIX problem when the pix configured for the syslog server with tcp port ?
I encountered this problem when I configured the pix for syslog server with tcp port..the command is logging host (in_if) (host_ip) [tcp/port_number].
Actually there is no problem when the syslog server was up. But when I shut down the server..the pix suddenly can not route packet from inside to outside..but if I did pinging from pix to outside and inside are ok..only if I pinged from inside network, servers which are in inside network, the packets are stopped at pix. the pix image version is 5.1(2). is there any bugs on that version ??
If you use udp (default) to syslog, if the syslog server becomes unavailable, the traffic will still flow through the PIX. All that will happen is that there will be no logs until the server is brought back online.
