[SOLVED] webmail access slowly from LAN zimbra 5.0.9 OSS ubuntu 8.0.4 x64

[pamulangnet]

fluent migration process of zimbra 4.9.5 OSS fedora 5 to zimbra 5.0.9 OSS ubuntu 8.0.4 x64

some problem of which we face if user access from outside ( WAN) quickly, but if accessing from within ( LAN) will be slowly

this matter differ from moment use zimbra 4.9.5 OSS fedora 5, accessing from outside or LAN very quickly.

user access webmail use or firefox of IE7

moment of installasi beside router there no and change of setting our equalize for IP.

we try and ping of tracert server via local very good

so on the internal LAN what IP range are you in ? does the router have firewall and proxy facilities ? from the ZCS server to a node on the internal LAN how well does that ping ?

Sometimes going out and coming back in through a NAT router can be slow. Make sure your LAN users resolve to the LAN IP and not the WAN IP.

thank of uxbod

firewall and proxy on my router is running, test ping from ZCS to router is good

we try againt and againt and againt.........


hmmm , likely my problem for a while solved, step which we try as follows :

1. setting in router use 172.16.10.254 default gateway as well as dns
request 202.xx.xx.18
2. setting in client is gateway use 172.16.10.254
while our preffered dns server of content 172.16.10.254
us change by 202.xx.xx.18
3. at client running command prompt and type ipconfig /flushdns
4. close and open firefox clear cookies and chache
5. close firefox and open firefox and run my webmail url
6. hmmmmm...amazing........ ZCS running cool and very quickly from LAN
7. test from outside quickly
8. test from dialup (you knows dial up connections in indonesia very slowly max 56 kbps :mad ) but we try access ZCS not to bad


hmmm, good ...good ...good and very cool ..... we like it

ok thank's uxbod and ZCS team
