It should be the standard setup - basically you are supposed to put a router on the /30 and then they should route the other IP addresses to that router. I normally would not like my device IP's (and that includes servers) to be directly attached to the ISP. Whatever I did in the last 15 years or so always had this setup, and I was always using a router / ...

While TomTom is correct based on his reading of the question, the OP might also be referring to a very common provisioning that ISPs do. The OP is calling it "LAN" IPs, but in reality they are WAN IPs assigned for his LAN "devices". An example would be: ISP assigns the "WAN" to a /30: ISP side = 1.1.1.1 WAN port on router = 1....

It depends what you want to do. PIX is still good.515e and 535 even the old 506e . As I said before it depends on your requirements of design.I still use and deploy them. Configure them good and they are solid. Devices and age ,old or new is not the problem. It is the person configuring them and whether it supports what you want to do. People think ,...

Yes. Several distributives based on Linux or FreeBSD can be used as soft router. By example DD-WRT, OPENWRT, BSDRP, ALPINE LINUX and many others. They can do all what can do Cisco router without proprietary protocols. But they need compatible hardware. Raspberry PI isn't good choice, because it has only one Ethernet port and low productivity. USB Ethernet ...

The PIX501 predates jumbo frames. Consequently the hardware does not support it and as such there is no way to enable it in software or configuration. Since the PIX501 is out of CCO / Safenet support, I would recommend to start planning to migrate to the ASA5500 series of devices, many of which support GigE and jumbo frames, and which can still get support ...

I can't find anything that suggests that the PIX has a maximum MTU of more than 1500, so yeah, it'd be a bad idea to have it acting as the router for devices speaking 9000 byte frames. Better question, though, is why is your network being switched to jumbo frames? It's unlikely that the minor performance benefit will make much difference in anything but a ...

An ASA will do everything the PIX did and then some, so it the replacement. You can pretty much drop a PIX config onto an ASA and it will run, so there's no way I'd buy a PIX today.
