I have a network configuration problem with HP-UX B.11.23 ia64. I want to use 2 
physical nics with IP addresses in the same IP subnet. I don't want to use 
teaming but the "Server network interface" feature from networker.

With one nic it works as expected, but with 2 nics i loose the complete network 
connection. If i configure the routing only for lan0 it works also, but lan1 is 
only reachable on the local subnet. 

INTERFACE_NAME[0]=lan0
IP_ADDRESS[0]=192.168.1.1
SUBNET_MASK[0]=255.255.255.0
BROADCAST_ADDRESS[0]=""
INTERFACE_STATE[0]=""
DHCP_ENABLE[0]=0
INTERFACE_MODULES[0]=""

INTERFACE_NAME[1]=lan1
IP_ADDRESS[1]=192.168.1.2
SUBNET_MASK[1]=255.255.255.0
BROADCAST_ADDRESS[1]=""
INTERFACE_STATE[1]=""
DHCP_ENABLE[1]=0
INTERFACE_MODULES[1]=""

ROUTE_DESTINATION[0]=default
ROUTE_MASK[0]=""
ROUTE_GATEWAY[0]=192.168.1.254
ROUTE_COUNT[0]=1
ROUTE_ARGS[0]=""

ROUTE_DESTINATION[1]=default
ROUTE_MASK[1]=""
ROUTE_GATEWAY[1]=192.168.1.254
ROUTE_COUNT[1]=2
ROUTE_ARGS[1]=""

With linux and windows this works without problems. Any hints for HP-UX?
