The command to enter a route that will direct traffic to the firewall is. console(config)#IP route 0.0.0.0 0.0.0.0 192.168.2.1 On the 7048 the IP address 192.168.2.254 needs to be for VLAN 10. And then no other VLAN should be in the 192.168.2.x broadcast domain. console(config)#interface vlan 10 console(config-vlan)#ip address 192.168.2.254 255.255.255.0 Then to relay DHCP packets to the DHCP server you would add a the ip helper command console(config)#ip helper-address 192.168.1.92 dhcp
Hi, We have a stack of 2x 7048s which are (is?) configured as the default gateway for a number of VLANs coming from some Dell blade chassis. I wont go into too much detail as it's more of a conceptual thing i need to know 8x VLANS, all of which are x.x.x.254, 255.255.255.0. Great. All the internal stuff works a treat. I now want to take port 48 and plug a juniper firewall into it and have all the internal stuff be able to acces the internet. safely. I can set up the Juniper and access the internet separately and it all works fine too. How do i join the two together? How do i configure port 48 to be the gateway for the internet for all the VLANS ? from the outside inwards the external internet connection (internally) is 192.168.1.254. It DHCPs my Juniper with 192.168.1.92 (UnTrust delivered by DHCP from the external router). Juniper Trust IP is negotiable but currently i have it set as 192.168.2.1 (static) and was going to have the port set as 192.168.2.254 So its the conceptual bit of getting all the .254 VLANs to see port 48 as the exit to the internet i'm lokoing for. Then i need to set up DNS etc internally and on the Juniper which is the next challenge. Thanks in advance    
7048 config as default gateway. Next hop Juniper and internet
