It's something to look out for though. We wasted a lot of time on debugging the first one.

Carriers blocking IPSec...official policy?
by rob.edkins＠axon.co.nz 08 May '02

08 May '02

Greetings folks, We have had several instances recently of problems with IPSec VPNs that turned out to be caused by ACL's at the ISP or carrier level blocking ESP traffic, or rather any IP traffic that isn't TCP, UDP, ICMP or routing stuff. There is no one particular network provider involved (one was offshore), and it doesn't seem to be a general practice, but we seem to be getting caught occaisonally by default "deny all IP" catch-all rules of the kind you stick at the bottom of the access list. Sometimes, it's only one interface in a particular direction. We've wasted a large amount of time and effort debugging and trying to get people to check their router configs for us, with varying degrees of co-operation. Has anyone else struck similar issues? Can anyone comment on whether this is a general 'no VPNs on our turf' policy, as one provider's help desk has (not terribly helpfully) suggested?

Mailwasher.
by Simon Lyall 06 May '02

06 May '02

Are other people having problems with customers using this program? It has a function for "bounce" spam which forges bounces from MAILER-DAEMON at the ISP's domain. I seem to only have a very small number of customers using it but the queues on my mail smtp servers are growing a bit with emails to bogus addresses waiting to time out (which is why there is a seperate server for bounces in the first place). I'm really worried that if use of the program takes off I'll have to re-resource ($$$) my mail servers to take account of a few 10,000s emails sitting in the outgoing queues or else the same customers will start blaming me for not delivering their emails in less than 10 seconds. I think the author is from New Zealand, anybody know them , an address where I can send a bill would be great. I also really object to the concept of the program forging email addresses on emails. -- Simon Lyall. | Newsmaster | Work: simon.lyall(a)ihug.co.nz Senior Network/System Admin | Postmaster | Home: simon(a)darkmere.gen.nz ihug, Auckland, NZ | Asst Doorman | Web: http://www.darkmere.gen.nz - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

But not only does it let you delete unwanted emails before you download them, it also bounces them back so it looks like your email address is invalid." etc etc etc. They credit a "Christchurch businessman Nick Bolton" with the idea. <insert comments regarding LART'ing with large clue stick here> Cheers, Darrin - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

Hi Simon, I had a couple of customers using it, until I informed them that technically they were breaching our AUP (forging headers). I don't care if they want to use it for filtering, but trying to bounce to domains with bogus MX pointers just causes me problems. Once they understood the issue, they were quite happy to just use the filtering functions.

Re: FW: Walker Wireless attacking other ISPs?
by Steve Phillips 04 May '02

04 May '02

Sorry, this was supposed to hit the list Friday, but due to posting restrictions it never made it through :-) -- As the owner of this IP block, we were made aware of the issue, we requested that we be given until the end of the working day to obtain a response from the customer involved. We personally appreciate Gordon's restraint in agreeing not to post details on this until such time as the deadline was met or the formal response was obtained. Sadly, we did not manage to get a formal response to Gordon about this issue. The customer in question was null routed at the time, the block was removed pending comment from the customer but if this causes an issue for anyone else in the Internet community then please let us know and the null will be re-instated. Thanks, -- Steve.
