Cisco 851W configuration help

I have a CISCO 851W router, purchased a few years ago. I need help to perform the following tasks: 1. Upgrade the flash (If one is available on CISCO's site) 2. Guide me through SDM or Telnet to setup the following: 2a. FastEthernet Port for access through Cable company (DHCP) 2b. Dynamic DNS 2c. Wireless interface with WEP 128 Bit 2d. VPN 2e. NAT ( A few will do), I can manage the rest later 2f. Secure the router I am somewhat familiar with IOS? commands (5 out of 10).? I can be your eyes. I believe that if you know your stuff, this is not a big job.? However, I prefer someone who can be on phone with me or may be chat (I do have another router).? But chat can go offline while switchign routers, so a phone backup is still required. If you want to guide me through email, that will be fine too. ## Deliverables You can send me configuration with step by step instructions starting with Factory default settings.
