comment ISP like Linux WAN router/gateway
Is there any reason you can't use a device that is designed for this exact purpose, such as an edgemarc, sonicwall or cisco router? They require minimal setup to do what you are looking to do, will generally have lower maintenance and power consumption, and are easily configured to handle snmp and telnet or ssh services as well.

comment Cisco ip phone set-up
The first thing you should probably do is factory reset the phone so that you have full access to the configuration menus. After that, the conf is based on whatever VoIP system you are using. You can find the admin guide for the phone here: cisco.com/en/US/docs/voice_ip_comm/cuipph/7906g_7911g/6_1_3/… To factory reset it, see the "Resetting or Restoring the Cisco Unified IP Phone" section.

comment Understanding IOS Firewall
I have never seen an ACL that when active doesn't implicitly deny that which is on the accept or allow list. There should be no reason to use anything but the allow statements where necessary.

comment slow DHCP leasing
have you tried a tcpdump (ports 67 and 68 for DHCP) to see what is happening with the signaling when a computer is sending a DHCP request?

comment How to stop spammers from sending spam as me
Its just like snail mail. Anyone can write your address on the envelope to make it look like you sent it, but it doesn't mean you did. In email its just changing a few fields of data to have the same effect.

That slight change in speed will hardly be noticeable compared to the gain of 1 GB of RAM.

comment Changing name servers for website only
the nameserver holds your records, you only need to change the records associated with what you want to happen, not the entire nameserver. You may mean A records, not nameserver in this case, that is what is associated with domain name to ip resolution.

comment Ethernet switch capacity question
more or less, but there is packet overhead and the ability of the switch CPU to cycle the information of 48 ports at one. If its a switch designed for this, no issues, but if its a set of daisy-chained 12 ports, there will be major issues. Its all in the equipment that you choose.

comment Getting My “Foot in the Door”
installation work is good, it gets you familiar with the equipment, standards and especially layer 1, which can be VERY important in troubleshooting issues later. I can't tell you how many brilliant techs fail to solve certain problems because they don't even consider wiring as an issue.

comment DNS Configuration: Am I doin' it right?
It may take some time for the changes to propagate. Some hosts can take 24-48 hours, some will have it updated in 4-6 hours.

They are faster (1 query vs 2 queries). It is especially useless when you are just looking at the same server, CNAMEs are best for pointing to a server outside your domain, see this article: rscott.org/dns/cname.html
