<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">New implementation of IPV6 in our mobile network. We are in the testing phase which so far is proving unsuccessful. We have configured the interfaces, routing in OSPF/BGP of IP Pools plus NAT64 for DNS resolutions. Sometimes during a browsing
test no security flow sessions detectable on firewalls When browsing succeeds the latency is very high such that service quality is very bad. We will appreciate a troubleshooting session to see if all is OK at the level of Juniper switch and firewalls. We
will appreciate a troubleshooting session so you can advice on what can be done in this case<u></u><u></u></p>
