Hi
Just averted a nasty disaster and I had a question, forgive my noobness as I'm not a router guy but they are trying to make me one. Last night we had a cisco guy come in and tighten down one of our routers that borders our firewall. We had to delete all our access lists and recreate them as such we had to create permits for all the various ports. As part of our access statement we used "tcp permit" for 110 and 25. Well it turned out that by doing this mail came in but didn't go out. I started to think about it and with some of the IP stuff ive been reading about I thought maybe smtp isn't part of tcp and maybe its part of udp. Well from what I am told a statement of "ip permit" should cover it wherever smtp may fall. In this case it did, the new permit did work. My question is, where does smtp fall? Should I have used a "udp permit" statement instead? e- _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
