Ignite boot_helper problem

[catastro]

Hi all. I have my Ignite Server on a different subnet of another HP-UX client. These are the details:

Ignite Server IP: 10.57.224.75
Ignite Server Gateway: 10.57.224.2
Ignite Server Netmask 255.255.254.0

HP-UX Client's IP: 10.57.230.151
HP-UX Boot Helper: 10.57.230.150
Subnet Gateway: 10.57.230.2
Subnet Netmask: 255.255.255.0

The client and boot_helper are two partitions on a rp8420 server, and the boot_helper is up and running in the OS.
On my boot_helper I have all the ignite software installed already (same version as the Ignite Server), and in the client as well before doing the make_net_recovery.
I followed the Admin Guide for Ignite-UX and tried to configure my boot helper system as follows:

- In the /etc/opt/ignite/instl_boottab file I have an entry with the IP of the client (10.57.230.151).
- The output of instl_adm -d is:
server="10.57.224.75"
netmask[]="255.255.254.0"
route_gateway[0]="10.57.224.2"
route_destination[0]="default"

In my client's BDH I execute the command
bo lan.10.57.230.150 install (boot_helper IP) and I get this:

BCH Directed LAN Path: 1/0/0/1/0.10.57.230.150


Do you wish to stop at the ISL prompt prior to booting? (y/n) >> n

I don't have any idea of what is wrong in here. I already tried modifying the gateway and netmask of the instl_adm command, but always says the same.
I have a firewall in the middle, but it does not show anything (it is configred for showing up all the packets that can come through and the ones that are blocked as well).
It is like the boot helper does not know how to contact the ignite server.
Could anyone help me to sove this issue? As I have looked through several guides already, and in the forums as well and did not find anything at all.

Done. After looking a lot, I have found that the ignite server needs the lan0 cabled in the ignite server lan and it can not be used (only in PA-RISC servers; for Itanium is not needed).
