    Cisco ASA 5512-X Boot

    Yes they are old, but you can see how they handle their "NGFW". I would not trust them at all.

    beginner NGFW questions

    For small company definitely Meraki as Charold suggested. Meraki integrates with SourceFire which is pretty good solution. For bigger companies you need to thing as dedicated box for some services. Problem of UTM is performance when you enable all enhanced features. Not enough CPU power on...

    Cisco ASA 5512-X Boot

    This is a real BS. Fortinet is good just for the flower stand and nothing more. Just keep the ASA5512X, install 9.3 SW and consider to upgrade to SF (just need a SSD disk upgrade + license for FireSight managment and you are on the horse). Palo Alto is even worse. Check this...

    Replace Fortigate 311B cluster with?

    I would argue this, since SourceFire/Cisco is a market leader by far. Just check the NSS labs for testing the products and you will see that SF is the winner for last 4 years. I would suggest to you to check the SF solution.

    securing a PBX

    Usually you have FW in place to do the SIP inspection. Behind the FW you should have enterprise CUBE/SBC box which will use SIP trunk authentication with the SP which is providing the SIP trunk. CUBE/SBC is kind of FW for voice traffic. Some related papers...

    Weird routing problem (PFSense, Cisco 3550)

    Weird routing problem (PFSense, Cisco 3550)

    Can you ping from VM (VLAN2) to IP Address of VLAN3? Can you ping between VMs in different VLAN? You need to find out that VLAN routing is working on Cisco 3550 switch. If this works then you can add Pfsense.

    Weird routing problem (PFSense, Cisco 3550)

    Remove this command "vlan dot1q tag native". You have specified that VLAN1 (native) is also tagged, but ESX does not expect to get tagged traffic for VLAN1, since ESX does not tag VLAN1. Or change on ESX to tag also VLAN1. This should solve the problem.

    Try to check also Catalyst 4500x, but still I would prefer N3K.

    Best 10GbE Switch on a Budget?

    If you want to have serious DC solution that you will think about Nexus 3k or 5k it depends on what kind of features you need. If you need SDN prepared DC network then look at Nexus 9k. If you will have blade centre think about Cisco UCS. Check UCS you will not be disappointed.

    Ubiquity EdgeRouter Lite or Mikrotik RB750GL

    Since you know Cisco equipment you could go with ASA 5512-X + L2 gig switch and you can do all of those things you would like to do.

    Need iSCSI switch

    For iScsi you need larger buffers on switch and also larger MTU size. Be aware of this.

    10gbe switch

    As always the answer is depends. If you need this for Enterprise DC, then you need something like Cisco Nexus5k or maybe Cisco 4500X. If you need for home usage, then look for Netgear, but do not expect very good performance.

    Cisco 2960 + iSCSI Problems

    Did you change MTU size on switch. For iSCSI traffic is recommended to change MTU. Check it with "show system mtu". On 2k/3k you need to set it for the whole system. Change it to biggest possible: system mtu jumbo xxxx

    Linux and MacBook wireless issues on enterprise network?

    What kind of authentication/encryption you are using? I haven't seen any problems with the linux/mac/windows on wireless network (roaming) using Cisco equipment and using PEAP+AES or EAP/FAST+AES on several networks. Push Aruba to fix it.
