Good Morning I tried to review the threads for this issue, but it seems I could not find anything similar, OR I just missed it. This might come across as a little confusing.... I am running a switch expansion project for a client, they currently have 2 MS-250's stacked as the Core. I am adding 2 new 250s as well as adding 225 stacks in each IDF closet, removing old Dell switches. The client has a PC and MAC network, all elements of the network (wifi, servers, workstations) all in their own VLANs. I am attempting to replicate the environment in my lab and have configured the transit network (172.16.1.0/24) on an unused interface on our SonicWALL. I have configured all the Layer3 Routing as it exists on the prod switches. But unless i am on the 172 network, I am unable to reach the internet. If i plug into say port 9 of the core and assign that port VLAN 1000, I connect. If I change it to say VLAN 3 (10.3.3.0/24) I do pull an IP address within that subnet however I am unable to traverse out. I am ready to share the configs that I have so far, and am about ready to call into support, but I think there is just 1 stupid, little thing that I am missing and was hoping one of you geniuses might be able to assist. The first image is the development in my lab (TJP-Core4) the other is Prod (TJP-CoreStack) Development Prod
