Could not open outbound connection?

Post by Peter » 10 Sep 2008, 09:05

This FAQ applies to:
  • Clavister CorePlus™
Question:
When i perform a ping from the console i get the following message : "Could not open outbound connection?" What is the reason for this?

Answer:
There are alot of reasons for this, these are the most common, and uncommon, ones.
  • * Failed to find a route to the destination IP

    * Failed to find a route to the source IP

    * The connection table is full (and conn-replace fails)

    * Failed to acquire a new ICMP ID or source TCP/UDP port for NAT'ing

    * UDP Src Port 0 is specified, but not allowed (by setting)

    * Failed to acquire an IP from the NAT pool

    * SLB fails to apply the configured policy

    * Threshold rules does not allow a new connection at this stage
"Failed to find a route to dest/src IP" is the most common cause.

Note: Depending on your CorePlus version some of these reasons may not be available.
