Re: [iMS] TCP/IP Filtering

Thanks Brook,
 
I did notice that the POST mod. would work when I "permit all" udp ports. I guess this has to do with how udp works. Thanks for your reply !
 
Best to All,

I don't know, have you tried disabling all TCP/IP filtering. If so, does it work when you do? At least you can pinpoint the problem to these settings and then work backwards to fix the problem.

I did a quick search for you on 'allow dns and "tcp/ip filtering" and found the following:

Also, all the search results are here

Thanks Brook...
NSLookup from the command line does fail. However, I don't understand why?
If the udp port 53 for dns is allowed, why is it failing? What am I missing?
 
Thanks.... (-:

If you can't do a nslookup from the command prompt then MX lookups will also fail from within IMS or rather from the DNS server listed in IMS in the POST server settings.

Can you give some more details?  What do you mean by iMS won't work? Which part?

I'm not sure what would cause this but you can try doing an nslookup from the command prompt - if that doesn't work then iMS won't work.

Thanks.... I am running Win 2k Server and go to TCP/IP filtering. I am
permitting only TCP 25 and UDP 53. After reboot I get this in the POST log:
12/01/2003 03:33:11 PM [001] WARNING: No MX found from server 129.250.15.61 for domain.com: [LOC:1 / Sock receive] Socket Read Timeout.
Any suggestions?
Thnaks...
