Can i access a different network

I have one network (company) using a subnet of 10.0.3.0/24. I have another network (company) across the hall using subnet 10.0.14.0/24. I have a punch down in each rack that connects me to each network, internet redundancy. what i would like to do for some minor file and print services and mostly administrative tasks is gain access through each network using a wired network.

Couple ways of doing this.

1) Router with 2 ethernet ports.
2) routing switch
3) 2nd nic in your PC, one for each network so that PC alone can access both

ok the switch i have is a layer 3 switch. HP Procurve 2512, 12 port 100mb. the address on that switch is 10.0.14.0 and the network i am on is 10.0.3.0. I am familiar with vlans and ip routing on a switch, but i am confused on the routes???

Not to concerned with dns or wins, ip only is fine........

Not sure I'm totally following you. You have both 10.0.14.x AND 10.0.3.x plugged into same 2512?

Or is it that the 10.0.14.x is in the 2512 and you and 10.0.3.x are on a separate switch not currently physically connected to the 2512.

correct, we are not connected in anyway yet. seperate networks seperate switches

Michaelj42Commented:
ok, you need some type of routing hardware between the two then. If you can enable layer 3 routing on the 2512 perhaps it will do that for you, it has been a number of years since I've touched a procurve so I can't say off the top of my head. Any 2 eth port router should do it.

unfortunately i dont have any available interfaces.

2 questions > what would the routes be?

would the ip routing on the 2523 effect current netowk flow, as far as gateways. On the 10.0.14.0 i have a data vlan and a voice vlan.  10.0.14.1 is the router 10.0.14.2 is my gateway for my lan.

How do your two networks hit the internet?

Michaelj42Commented:
In your initial question you said: "I have a punch down in each rack that connects me to each network, internet redundancy." I assumed from this that you have two separate internet access points, one for each network and, presumably, some type of DSL or Cable router at these points. You asked later how routing between the two networks would affect network flow. To answer that I'd need more details about your current routing to the internet.

sorry, there for the confusion. There would be a few ways to answer. Each network is connected to the net via a dedicated t1 with same service providers.

Michaelj42Commented:
OK, what type of router does the T1 connect to?

armitdeptAuthor Commented:
both networks have an HP Procurve 7102dl.......

God damn HP Procurve, scares everyone away......

Michaelj42Commented:
sorry, I'm not familiar enough with the procurve to tell you specifically how or even if you can setup route statements on a procurve. I assume you can but haven't done it.

Basically you need some type of router between the two networks. Your default gateway (the procurve 7102s) (or your PCs if you want to do manual route statements) needs to know that to get to the other network go to this internal router, not the internet.

So on your procurve on the 10.0.3.0 network it would have route statements like this:

10.0.14.0 255.255.255.0 10.0.3.2 (or whatever you made the IP address of the internal router)
0.0.0.0 0.0.0.0 [WAN port]

This would tell it that for any traffic going to 10.0.14.0 network send it to your internal router, everything else send to the internet. You'd setup the opposite side the same way using the addresses for that side.

Make sense?

Absolutely makes sense. This is my plan and have done it in the past. Just lacking funds. Sooon hopefully!

Thanks,
