This added the route, however, I am still not able to ping to 10.67.26.89.
The route command says the following: if you got a packet for 10.67.26.89, then send it to 10.61.1.1 and the host owning this interface will know how to deal with it. Do you even get to 10.61.1.1? If not, this is the problem! (Tip: if you use ping to test specific connections you assume that the ICMP protocol - which is used by ping - is allowed. This is usually not the case in firewalled environments. They usually drop ICMP packets silently.

Use this:
Code:
telnet <targethost> <targetport#>

for tests then. You won't get a telnet connection at all, but you will find out if you get even there (connection attempts fails, usually with some banner from the application waiting behind the port) or not (connection times out with "host unreachable" or so).

In general systems should not know how to route (quite like routers should not do other work besides routing). This is why you should not explain to the routing table of your system about how to use the foreign address 10.61.1.1 to get to some remote server because you need to tell it how to get to 10.61.1.1 itself first. Let the routers decide this and tell the system which interface to use to send the packet:

Code:
# route add net 10.67.26.89 netmask 255.255.255.255 <your interfaces IP> 1

and the router adjacent to this interface should be able to forward it on its own. Otherwise your network design is flawed.

I hope this helps.

Net::Server::MultiType(3)				User Contributed Perl Documentation				 Net::Server::MultiType(3)

NAME
Net::Server::MultiType - Net::Server personality SYNOPSIS
use base qw(Net::Server::MultiType); sub process_request { #...code... } my @types = qw(PreFork Fork Single); Net::Server::MultiType->run(server_type => @types); DESCRIPTION
Please read the pod on Net::Server first. This module is a personality, or extension, or sub class, of the Net::Server module. This personality is intended to allow for easy use of multiple Net::Server personalities. Given a list of server types, Net::Server::MultiType will require one at a time until it finds one that is installed on the system. It then adds that package to its @ISA, thus inheriting the methods of that personality. ARGUMENTS
In addition to the command line arguments of the Net::Server base class, Net::Server::MultiType contains one other configurable parameter. Key Value Default server_type 'server_type' 'Single' server_type May be called many times to build up an array or possible server_types. At execution, Net::Server::MultiType will find the first available one and then inherit the methods of that personality CONFIGURATION FILE
"Net::Server::MultiType" allows for the use of a configuration file to read in server parameters. The format of this conf file is simple key value pairs. Comments and white space are ignored. #-------------- file test.conf -------------- ### multi type info ### try PreFork first, then go to Single server_type PreFork server_type Single ### server information min_servers 20 max_servers 80 spare_servers 10 max_requests 1000 ### user and group to become user somebody group everybody ### logging ? log_file /var/log/server.log log_level 3 pid_file /tmp/server.pid ### access control allow .+.(net|com) allow domain.com deny a.+ ### background the process? background 1 ### ports to bind host 127.0.0.1 port localhost:20204 port 20205 ### reverse lookups ? # reverse_lookups on #-------------- file test.conf -------------- PROCESS FLOW
