host is not responding back with TCP SYN-ACK in response to TCP SYN by another host

Hi 

We are  unable to connect hp unix server (IP 10.1.150.200) from another server (IP 10.59.7.29) .

The same server (IP 10.1.150.200) I can able to access through another VLAN .

when we asked network team to analyze the same they repiled us that '"destination ip 10.1.150.200 is not responding back with TCP SYN-ACK in response to TCP SYN sent by source ip 10.59.7.29"  and need to check from server side.

Server is running - HP-UX B.11.31

Server Modle - BL860c i2

So I would like to know is there any setting needs to be changed from server side to overcome this issue?

Thanks in advance

Mandar

It sounds like your system does not the gateway (route) setup correctly. What does the command:
netstat -rn
report? If the gateway is incorrect or not specified, edit the /etc/rc.config.d/netconf file to add your router's IP address. Then restart networking with the command:

/sbin/init.d/net start
