It seems to me that a switch with a substantial port/packet buffer is needed to down-convert this connection from 1Gbps to 100Mbps in an optimal fashion. Thank you to everyone for their input and suggestions.Īnother Update - Out of curiousity I tried placing a consumer class, unmanaged 8 port gigabit switch (D-Link DGS-2208) on the outside and my speeds dropped back down to 35Mbps. For anyone using a Cisco ASA 5505, 5510, 5520 or 5540 in their home, lab or non-production environments and wants to be able to run ASA OS versions 8.3 and later youre probably going to be on the market for a memory upgrade. They are usually only set in response to actions made by you which amount to a request for services, such as setting your privacy preferences, logging in or filling in forms. The penalty that the ISP forces upon you when you have a straight 100Mb connection is pretty severe in this case. These cookies are necessary for the website to function and cannot be switched off in our systems. So I take this a step further a throw a Cisco 3850 switch in the mix and my download speeds are consistently testing at over 92Mbps now. So i placed an old Dell 5324 gig switch in between the ASA outside interface and the ISP Cable modem and immediately I start getting speedtest speeds around 80Mb down.

Update - Issue resolved per fphazer's suggestion. Is this a hardware limitation? I was under the impression that the 5505 should be able to handle up to a 150Mbps throughput (actually 100Mbps since all interfaces are only 10/100).Īnybody else using an ASA 5505 and getting more than 35-40Mbps download speed? Not sure the NSA bacon exploits work on 8.4 etc. I think there was a loop hole that they would give you access to a new firmware if there is a security bug discovered. I have attempted to hard set the interface to 100/full as well, but that just makes throughput worse. Reply 8 on: November 12, 2016, 06:23:33 am. Outside interface is configured for auto-negotiate and is negotiating at 100/Full. I have tried removing any service policies, opening up firewall rules, etc. If i bypass the ASA i get these speeds without issue. I have a 5505 firewall and recently upgraded our internet to 100Mbps down 20Mbps up. Hi, I would like upgrade my ASA 5505 with ASDM 5.2(2) & ASA 7.2(2) I made the upload of the last file asdm-602.bin and asa802-k8.bin For the asdm, it seems to made the upgrade via Properties/Device Administration / boot image config and choose the last version before reboot.
