HP Procurve VALNS Help !

[ICTNUT]

Might be worth adding ip route 0.0.0.0 0.0.0.0 192.168.0.2 to deal with any packets it doesn't know what to do with.

I have got that in place

I have just done a reboot of the HP Switch and did a release and renew on the pc in vlan 3 and hey presto an ip address from the correct range.

But no internet

Let me check my proxy filter..... runs off

does your proxy have the relevant static routes to return the traffic as it won't have a default gateway for the lan side probably

I agree, you will probably need to have static routes defined in your firewall for all vlans.

If you proxy is isa server then let me know and i'll send you some instructions.

Many thanks for the pointers guys, here is where we are at, POsting at home at the moment as there is not internet at school.

Proxy is a Bloxx box that handles all the filtering
Firewall is a Sonicwall appliance.

All DHCP Request are now being sent to the correct vlans with the correct IP schemes with VLAN seperation working a treat i.e CURRICULUM VLAN cannot access nor see the ADMIN (SIMS) VLAN.

I think the internet side of things could be to do with routing but there are 2 other core switches in the way which still need to be configured properly so I will do this tomorrow after Ihave setup a dialup connection to the web

Will let you all know how I get on and thanks again for the pointers

Nice one. You just need some static routes to route back to your subnets.

[SYNACK]

You may need to configure all of the address spaces used by your vlans as part of the internal network in the firewall and will need to add static routes for each of these networks into the firewall machine itself.

This will allow the firewall to return packets from the internet via your internal router and still forward packets for any subnets that are not directly connected to it by sending these out to the internet.

OK here we go.

Thanks to all those that helped with the VLANs, easy once you get the HP terminology worked out.

Any how I have now got the issue of no internet feed to each of the subnets with my setup being as follows:

VLANs -> Proxy -> Firewall <- I get nothing of the internet in this setup

VLANs -> Firewall <- I get nothing of this setup unless I change the Gateway on one DC to the IP of the Firewall and hey presto Internet (this is how I am posting at the moment.)

Any ideas on how to get this sorted ideally as VLANs -> proxy -> Firewall

Proxy is a bloxx TVT-500 box and firewall is a sonicwall pro 3060 firewall

[ICTNUT]

All done, all sorted and all motoring

Need to setup the firewall with sub interfaces for each VLAN and I forgot to add a static route on the second HP L3 switch which just so happens to be the one the firewall is linked to.

Did the above and bingo
