ACL's with NAT
Burt, No, I dont have to restrict outbound traffic but I would have thought it would generally be good practice to restrict outgoing to your own IP address range. If ISP's did this imagine how much better the web would be with no infected pcs with spoofed source ip's flooding the net with... -
ACL's with NAT
Hi Guys, I have set up a 1721 as a nat roter on my broadband connection and it all works great. What I know want to do is lock it down as at the moment port 23 is wide open amongst others. I dont want anything fancy just local net out and nothing coming in except established connections. I... -
Postfix on MAC - I think it is sending spam?
Check your postfix logs and see what mails are being sent. I had this kind of email arriving and started to think I might be relaying spam but after a bit of digging the mails turned out to be cleverly worded spam. Jon Jon - CCNA to be :-) UK- jonny2495

Is this possible
Hi Guys, I am running a postfix server that collects mail via fetchmail. The mail comming in is already spam checked and is flagged as such in the header and subject.

2500 Serial ports
Hi AK, Sorry, I must not have explained myself very well. I am already using the ethernet ports and everything is working great. I have just connected a 2501 to my 2514 via the async serial ports and that works a treat. What I am wanting to experiment with is what else can I connect to the... -
2500 Serial ports
Hi all, I have a couple of 2500 routers that I am playing around with as part of my CCNA training. I have been thinking about what I could connect to the serial ports apart from another router with a crossover cable. So......... Would it be possible to connect my linux server if I fitted an... -

DHCP Question
Hi T0mm0 I had read that post and tried to see if it would affect my set up but it didnt help. The NAT and LAN side of things Iam OK with. I have already tried that and it orks great. Because of the problems I am having with on the WAN interface I have removed all other config to try and... -
DHCP Question
Hi Joamon Thanks for the response. My modem handles all the encapsulation etc and that side is working OK. The communication side is working OK as I am getting an IP address from my ISP. Having had a futher play around I have realised that when I plug it into my other router it gets an IP... -
