I'm sure others will chime in with more specifics. I've no clue on what 802.1Q is. One thing to keep in mind with your proposed scenario is that the WAP will provide a path to the 400, granting a possible attacker the means to access the system. Better would be to have the network link be something like WAP <-> Firewall <--> AS/400 (or regular LAN) with the firewall filtering everything out except what your scanners need. If you do proceed with WAP <--> AS/400 direct, be sure to close off all services possible on that Ethernet line. Also make sure the 400 won't act as a router and let wireless traffic into the regular network. Either way, you should probably also SSL-enable the wireless devices (if they aren't already) and change the default IP ports. WEP and other inherent wireless 'security' is miserably inadequate. - John -----Original Message----- From: Mark Allen [mailto:mallen@xxxxxxxx] Sent: Thursday, June 19, 2003 10:07 AM To: midrange-l@xxxxxxxxxxxx Subject: Network ? /*STRNETWKIGNORANCE Hope I can make this clear enough so someone can answer. We are getting ready to install wireless access points for RF scanners to access our AS/400. My network guy is concerned with putting them on the same LAN as the rest of our devices since if anyone did manage to access the wireless access points they would then have access to our entire network. What he wants to do is install a 2nd NIC in the AS/400 (have call into BP on that now) and put the wireless devices on that LAN. Here comes the part when I am just going to quote him as I have NO idea what he is talking about. He needs to do if the AS/400 will support 802.1Q data tagging as he says he needs that to support the 2 virtual LANS??? Any tips, links, explanation would be appreciated!!! /* ENDNETWKIGNORANCE Mark Allen IS Manager Wilkes Telephone & Electric 11 W.
