I work in sme 8.0

1) Is the sme8.0 fully updated with latest updates ?

Connected with Cisco firewall router behind back of server(Cisco 800)
and cisco router used as gateway in side sme mail server as IP 192.168.1.254

2) Can you explain that again more clearly, it is rather confusing trying to understand what you mean, is there one Cisco router or two ?

suddenly when i try to ping to external IP 78.93.244.61 it give me
request time out

4) Where do you try to ping from, on a workstation, on the sme server ???

this is my settings it work OK before and  send and receive but now not work

5) When did it stop working ? What things did you do or change immediately before "it stopped working" ?
ie what has happened to your settings, your equipment, your network layout, installed software (on workstations & server), Cisco router settings & hardware, ISP plan & connection etc etc etc, since the last time you were aware that "it worked OK" ?

the problem ping to external IP not reply and status of access internet is failed

6) Have you looked in log files on your server, workstation & in the gateway router ? Where you look at the log files will depend somewhat on where you are pinging from.

*yes sme fully updated
*i try to ping from workstation not from  mail server
*Only one Cisco router with gateway 192.168.1.254
*nothing happen OR changes suddenly cannot ping to external IP
nothing changes in equipment
i can ping or connect good to mail server locally
problem only when ping to external IP
*What i write to see log file

IF remaining information need i can supply you

[ahmedsa]

Can any one help me

[Stefano]

did you call your ISP?

[Stefano]

moving to SME8.X forum since it's OT in Contribs' one..

[ahmedsa]

We need to determine first the problem
then call ISP

[Stefano]

well.. if restarting the router make things work just for few seconds, I guess something is wrong with your router or with your connection.

in both cases, you'd call the ISP and check everything is ok with them..
if you had problems in the past days (and IIRC you had), maybe your ISP blocked you (I've seen such things many times)

[ahmedsa]

Can you tell me
if static IP not reply when ping
what i check
i don't have internet on static IP
I cannot access internet on this ip
i call company isp
it tell me every thing work OK
please can you help me

[Stefano]

since you are pinging your external IP on your cisco router from a workstation with fixed IP, can you tell me in which way SME is involved?

moving it to General Discussion

[Stefano]

trying to ping 78.93.244.61 from here.. request time out..

told so, you:
- may have your router blocking incoming IMCP packets
- may have some network issues..

in any case, since SME is in server only and I'm quite sure that who'd echo to ping is the router, it's not a SME issue.

you say that ISP told you everything is working ok.. well, it's not
