Virtual Server configuration
We own a 10.2.2 build installed on 1600 box(ltm licensed/provisioned) and facing an issue with configuring the
virtual-server's port in ltm.
Sample config is given below:
) list ltm virtual vip1
ltm virtual vip1 {
destination 172.10.13.45:13000
ip-protocol tcp
mask 255.255.255.255
pool Linux
profiles {
http { }
tcp { }
}
snat automap
}
) list ltm pool Linux
ltm pool Linux {
members {
172.18.78.60:13080 {
session monitor-enabled
}
172.18.78.60:13081 {
session monitor-enabled
}
172.18.79.51:13083 {
session monitor-enabled
}
}
monitor gateway_icmp
}
And, self-ip, vlan everything is configured with default values of 10.2.2. And, pool members are pingable from bigip. Client
also reachable to vip1 and physical servers.
An SOAP server-application is running in these three servers(172.18.x.x) in the given ports. When I try accessing these
servers seperatly using our SOAP-client application its working fine. (Note: The SOAP application is developed by us).
However, when I configure a vip server(vip1) to load balance between these servers, it fail to respond and reply a service
error saying "Server not running"(an error message sent by our application).
Up to my understanding, we can use any port in vip, irrespective of the actual server-ports. And, there is no firewall
between bigip and actual-servers.
We use our own SOAP client to access the Server-application. Through browser, we use our WEB-INF file via apache server to
access.
Can anyone help in configuring the port range of 13000-130080, instead of actual ports. Since this is an urgent requirement,
can someone suggest what is wrong here.
- Sasi_81631NimbostratusThe vip1 is replying when I use a port 13081 instead of 13000.
- hooleylistCirrostratusDo you have a virtual server defined on port 13081? Or is it matching a wildcard port virtual server? If the VS is defined on port 13000 your requests on port 13081 shouldn't be using this VS.
when CLIENT_ACCEPTED { if {[TCP::local_port] >= 13000 and [TCP::local_port] <= 13080}{ Do nothing and allow the connection through to the pool } else { Reset the connection reject } }
