server initiated connections, CSM - Default Gateway ?

Hi !

I am trying to configure server-initiated connections. As the server needs to access several destinations - I need to configure a default gateway.

I did:

vlan 110 client

ip address 172.16.110.253 255.255.255.0

gateway 172.16.110.50

alias 172.16.110.254 255.255.255.0

vlan 130 server

ip address 172.16.130.253 255.255.255.0

alias 172.16.130.254 255.255.255.0

static nat xxx.xxx.xxx.xxx

real 172.16.130.10

static nat yyy.yyy.yyy.yyy

real 172.16.130.11

The server has configured the Alias address as a gateway - but the CSM does not send the request.

When I enter a "route xx.xx.xx.xx /24 gateway 172.16.110.50" command it works..

BUT...

I need to access several destinations - not only one...

Doesn`t it support a default-gateway configuration ?

I would really appreciate any help...

cheers

Re: server initiated connections, CSM - Default Gateway ?

Hi Hans,

Another way to do this is to create a dummy serverfarm for the outbound requests.

Something like this:

Nat pool test 10.10.10.1 10.10.10.1 netmask 255.255.255.0

vserver outboundnat

virtual 0.0.0.0 0.0.0.0 any

serverfarm routeout

vlan servervlan

inservice

serverfarm routeout

no nat server

nat client test

predictor forward

When a device in the server vlan initiates a connection it is caght by the vserver and

will be client natted to the natpool address and routed out by the CSM.

This is how many people setup outbound server initiated connections.

Re: server initiated connections, CSM - Default Gateway ?

do you have another gateway configured on a different vlan ?

The CSM will only use 1 gateway. The first one configured or the first one to respond to arp request after reboot or failover.

So, if you have another gateway configured, that's the one the CSM will use to forward the traffic.

Configuring a vserver with a 'predictor forward' serverfarm won't change anything if this is a routing issue.

Gilles.
