I have erecently installed a Meraki (Now Cisco) Wireless Access Solution for my company. I have configured 2 SSID's, one for Wiress access to our LAN and the other for Guest access to the Internet only. These appear to work quite well, however some users are complaining that the email clients on their cell phones do not work when using this Wireless System. Web Mail Apps work fine however.
Internet Access is via our Cisco ASA5520 and I strongly suspect this is the culprit. I have opened all ports associated with cell phones but still it does not work. Has anyone seen this kind of thing before?
Ok, so I have run a packet trace using the Meraki Access Point as the source. Using my cell phone, I try to sync my virgin mobile email account. I see packets going to a number of servers and used Reverse DNS to identify these. All addresses are for Meraki, Facebook and Samsung Social Hub. No attempt to connect to Virgin Media.
Yesterday I connected a dumb access point (Not Meraki) to our production network - tested - same issue. The common factor here is the firewall.
It's working now. It was something to do with my access-list. I had all the right ports in there but for some reason it was ignoring them. I stripped it out and allowed eveything outbound. Access is now restricted using the built in firewall on the Meraki Controller.
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
