  Ok I finally was able to get the management interface to work, but in a backwards way. I added an ipv4 interface with VLAN 10 and rather than setting the IP I let it get it from DHCP. It did, and it worked fine! I then put a static IP mapping in pfSense for the MAC and forced a refresh of the management interface and now it has the IP I wanted all along. I then changed the IP over to "static" on the switch. My question is why did it work via DHCP, but not via just setting it up as a static mapping? The only thing I can think of is that when I add the interface manually with a static IP it is doing something weird with the default route or not updating the default route and it's trying to access the management VLAN over a different interface. Anyone seen this before?

  @johnpoz said in Browsing nfs share in other VLAN not working.: @herman said in Browsing nfs share in other VLAN not working.: When the family is watching a movie and I start to copy large files the movie stutters or even stops. And the kids do not appreciate that :-) If your loading up the server, might not matter if your on another interface or not if your sucking up the I/O to a shared disk or CPU of the machine. If your on a switch you doing something between A and B doesn't effect traffic between C and D.. Adding another interface on B, will only solve the problem of stuttering a streaming movie if the only problem was saturation of the interface.. But if your working with the same disk that the movie is streaming from... Your issue might not be network bandwidth it could be your hitting the I/O of the disk limits, or the cpu of the server streaming, etc.. Thank you @johnpoz for the info... I wil dig in it.

  You will definitely want to do a fair amount of planning and schedule an after-hours change window because there will be some downtime. You'll need to configure a transit network, configure the SVI's on your switches, if dhcp was previously coming from PFsense... you'll need to figure out where your new DHCP server is going to live, add helper addresses to each SVI, change the default gateway for all of your dhcp scopes, change the default gateway for all static devices, etc. There's quite a bit of work to do, but it will be worth it.

  Everything depends on your setup. Would need more details. Post a network map. Are your VLANs terminated on PFsense or your switch? Post your server1.conf What are the IP's in the VLAN you're trying to access? What do the rules look like on your LAN and OpenVPN tab?

  If you want to use the DHCP server from the Main Office, you need to set a DHCP Relay address on the Branch Office with the IP(s) of the DHCP Server(s) from the Main Office. So the branch office will sent the DHCP request to the Main Office.

  Yea, I've come to the conclusion short of getting new storage and putting it squarely in each VLAN that I need to do L3 routing at the switch for VLAN 20 and 70. I guess I was just more or less asking if there was any other architecture you can think of that may have worked better, but it really seems like it is that straight forward. So to summarize my changes: Disable Snort on VLAN 20 and 70 Create 172. something /30 subnet for transit Create new VLAN tag 172 in pfSense Create new interface tied to this VLAN At both switches I will add a new VLAN for the transit network, and set that as the default route to 172.something.1 Add VLAN 20 and VLAN 30 at the core switch (sg300-10). I'll put in ACLs to block everything between the VLANs except the IP\Port combos I currently have in my firewall relating to those two subnets. Disable VLAN 20 and VLAN 70 interfaces in pfSense Create new gateway with 172.something.1 as gateway Create new static routes for 10.37.70.0/24 and 10.37.70.0/24 via the gateway created above Enable Snort rules on new Transit interface. Verify any needed VLAN 172 firewall rules that are needed (shouldn't be any as this will only be used for outbound requests, correct?) Sound about right?

  at Johnpoz Thanks for that. I'll give it a go (the worst fate is that guests have no access for a while, but then I don't get a million guests a day and I have an unlimited-data 4G modem if my occasional guests are "unhappy"). I am "greenfield" in a sense -- I have total and exclusive control over my networks and report only to myself in the event of a disaster (yeah, I might get some $#1t from Madame, but there is always the 4G modem to calm her down). I have elected to move to "my-net 3.0" -- my decision was unanimous :) Why do I seek tagged admin? Most VLAN attacks go for VLAN1, or failing which, go for native-VLAN. I ask myself WHY should I have VLAN1 or native-VLAN connected to anything at all ... let alone to the admin heart of the network -- just seems a silly choice! Off to the mountains for skiing: you wont hear from me for a week or two, but I'll report back. Appreciate all the feedback so far. regards, Chris

  I installed with success. I set mikrotik like a Wisp AP - Bridge, I deleted DHCP rules and i create 1 vlan on eth5. In PfSense I created 1 vlan, in Interfaces / Interface Assignments I associate WAN with PPPOE0(em0) created in PPPs like a Link Type - pppoe. Now I have an Pfsense router with 1 single ethernet port for WAN and LAN. Thanks!

  I had to use PIMD. IGMP Proxy wasn't routing the information properly. It sure would be nice if PIMD was default in the GUI if IGMP Proxy isn't able to route multicast for items like HEOS and Sonos. I followed this tutorial.

  https://forum.netgate.com/topic/139859/sg-1100-running-real-vlans/8 the SG-1100 is essentially a router-on-stick in one case. You can't simply change the MAC of just the WAN port, as this is a switch port. You can assign the parent interface mvneta0 and then change it's MAC, which will affect all ports and create a conflict with the original device if it's still connected. So either get rid of the original device, put it on a different L2 if possible, register the SG-1100 MAC with your provider or return the SG-1100 and get a device with more dedicated interfaces. It really pays to research the hardware before you buy it.

  @derelict said in Add NIC as extra LAN-port?: Get a switch. Leave igb3 available for use as a router port. If you insist on doing that look at bridging igb1 and igb3 into a bridge and use the bridge for LAN. I got a 5-port switch today which is in LAN but it's full, and I want to buy a Ubiquiti PoE switch 8-60W (about $100) but I only need 1 port so therefore it's not really negotiable to buy one just for I need one extra port lol So I thought if it's easy to use it as a LAN-port in the meantime...

  If you want all 4 ports to go to the same switch on 4 different broadcast domains then just connect all 4 ports to 4 untagged switch ports on 4 separate switch VLANS. Pretty much nobody would do that because VLANs are much more flexible but if that's what you want, knock yourself out.

  @johnpoz said in Moving device to new VLAN setup not working: you don't have any vlan 2 setup on your switch from what you posted You're right I don't have any vlan 2 setup now but from my readings for best practice if a vlan is created e.g.for port 3 for NAS then any other connection e.g. port 2 wlan interface 192.168.2.XXX should also have a vlan setup made. Correctly if I'm wrong. If i want the NAS device to go outside the network (e.g. internet) how will this work if it no longer has a wifi connection since the wifi router in on subnet 192.168.2.2 Do I have to NAT the NAS device to the wifi router? You have to create rules on those to allow what you want. I have a all open rule setup on the NAS interface but still was't able to ping the device using pfsense box under diagnostics however the gateway 192.168.30.1 succeeded. It may be my NAS device (wd mycloud ext2 ultra) giving me the problem. DHCP leases is displaying an ip for the device but it is showing it as offline. The unit itself is showing 3 blue lights indicating all is online.

  Not really. It works fine. The default configuration is DHCP WAN and 192.168.1.1/24 on LAN. All you have to do is edit Interfaces > OPT1, enable it, and number it with something other than what is on any other interface (like 192.168.2.1/24), add firewall rules to OPT1 to pass the traffic you want to allow, and enable a DHCP server on OPT1.

  Thanks for the advice. I found some of it before I read your message but your message was right to the point. I had to read your message a few times to understand, the third rule was kicking my butt because I didn't include the DNS in the first rule. While this type of stuff is probably easy for many people, my goodness it's a lot to think about and keep track of. I mean, I do understand it but dang! So it looks like I have a VLAN that is isolated from everything except the printer. I will still use that 8 port switch as I desire to run some VM's on my ESXi machine on a separate VLAN and I need the switch that handles VTAGS to go between the pfSense computer and ESXi computer, so there was a benefit to having purchased it.

  [RESOLVED] The problem was in Traffic Shaper .. When I prioritized the traffic on the network using the wizard, I reported the speed of the WAN link, in this case, 20 mbps. So, as I checked, pfsense limited the network bandwidth to 20 mb (2.5 MB), including LAN and WAN. As this information is not made explicit in pfsense, I only notice when I deleted Traffic Shaper and set it up again. The solution I found was to report the maximum capacity of the circuit (1 Gb) to use the entire internal network bandwidth. Otherwise, the entire network is limited to the speed of the WAN link. I had done this configuration for a long time, but since the network was not segmented, the internal traffic was not through pfsense, so when I created vlans, pfsense limited the band ..

  its a good obfuscation then - looks like actual screen shot! Better to mention you obfuscated or use documented example networks and mention that ;) 192.0.2/24 198.51.100/24 203.0.113/24 2001:DB8::/32 Just saying ;) You would be surprised at some of the stuff you see around here people doing for real ;) Or just block out part of the actual address so its clear is obfuscation..

  If you tell pfSense to tag on VLAN 5, and the switch port connected to that has tagged VLAN 5, then your workstation needs to be connected to an untagged VLAN 5 port on the switch to have layer 2 connectivity to pfSense. That's the whole point.

  Two things that I forgot to mention are that I already have OpenVPN set up successfully for my normal network and that since I'm new to the pfSense concept, I've never worked with VLANs on it before. I do, however, understand the VLAN broad concept since I've taken a Principles of Networking class as a computer systems administration student at my university.
