Need advice regarding performance of a Netscreen firewall
Posted on 2014-07-23
I have some questions I am primarily looking for advice on. We recently set up another remote office as part of our company network, and d/t the high costs of bringing fiber infrastructure to the site, we opted for a wireless WAN internet connection, at least for now. The provider has related that they are able to provide a connection up to 50 x 50 Mbps, and we have contracted with them for a 30 x 30.
After the install, I tested the speed at their POE block with my laptop and found the speed to be fairly close to the 30 x 30. I have a Netscreen SSG5 (256 MB) firewall in place at that office, and on the LAN side of the firewall I am seeing speed closer to 20 x 20 at best. In talking with one of the engineers for the provider about this, he is telling me that this is completely d/t our firewall, and that Netscreen firewalls are "sub-standard" in his opinion (and words). He is recommending that we instead install a Mikrotik router \ firewall device, provided by his company. He has gone on to say "I am not sure what they do in their Ethernet port programming, but whatever it is, they have it messed up across their whole product line from the low end stuff to their high end switches" when referring to Netscreen devices. I don't have extensive experience with multiple firewall products or enterprise routing and switching equipment, but I have worked with Netscreen firewalls for a number of years now and and typically understand them to be capable, if not robust. This is the first time I have run into this issue. Again, I agree that the speed on the LAN side of the firewall is slower, but I am trying to find out if his claims have any merit, or if it may be d/t the fact that the firewall in place is an older model. The remote office in question has about 15 users, and the firewall is configured with two site to site vpn tunnels.
Has anyone heard or know of any similar claims regarding Netscreen devices?
Does anyone have any experience with Mikrotik devices, and if so, can substantiate his claims of them performing far superior to the Netscreen firewalls?
I may also have an opportunity to try out a Netscreen SRX firewall as a proof of concept trial, and was thinking about trying it at that site to see if the speeds are any better. Does anyone have any information or advice regarding the performance of the SRX line vs the SSG line?
Thanks very much,
