Bandwidth Caping With PF

i have two questions actually...
i need to block certain ports with openbsd and PF in a large lan, the firewall is supposed to be a router between the internet and the first lan switch.
first of all, would this work at all in theory?
second, i tried doing this a few days ago at a huge lan but i just couldn't do it and still i was following all the OpenBSD.org instructions in their PF user guide, i did get internet working on the bsd box with a DNS server to connect to and two ethernet cards that worked only i could only connect to one of them not the other even though i had set an ip on both so i never got that firewall working so i was wonderig if anyone could help me.

second question is, would it be possible to in this lan mentioned above cap the bandwidth on most of the lan but not on the crews computers, and if this is possible could anyone point me to a nice tutorial about it or tell me how.

NAME
vtdaemon - respond to vt requests SYNOPSIS
lan_device lan_device ... DESCRIPTION
responds to requests from other systems (via local area network) made by (see vt(1)). spawns a server to respond to each request that it receives. Options recognizes the following command-line options and arguments: Causes to rebroadcast all requests received on one lan device to all other lan devices specified on the command line. The optional parameter ngateway specifies the maximum number of vtgateway servers that can be in operation concurrently. If ngateway is not specified, there is no limit on the number of vtgateway servers that can be in operation concurrently. Causes vtdaemon to ignore all requests that have come through a gateway. The remaining arguments are the full path names of lan devices that vtdaemon looks for requests on. If no lan devices are specified, the default lan device is used. The major number for this device must correspond to a IEEE 802.3 local area network device. Another function of is to create portals and service portal requests. A portal is a callout device that can be used by to communicate to another machine via local area network (see uucico(1M)). Portals are created by according to the configuration information found in the file Each line in has the format: <calldev>[,<lan device>] <nodename> For each line, creates a portal named calldev in Whenever this device is opened, spawns a server that creates a connection to the system specified by nodename via the lan device specified. If no lan device is specified, the first one specified on the command line when was started is used (or the default lan device is used if no lan devices were specified on the command line). should be terminated by sending signal to it. When receives this signal it removes all of the portals it created in before exiting. DIAGNOSTICS
