Hi,
I am using SME 7.6.
This server is connected to an ADSL modem.
I have also another Netgear gateway/router connected to the same modem used as a gateway for specific client computer within the company.
Both gateway have public IP addresses.
Since yesterday, clients using the SME server as a gateway cannot access at least two websites:
www.textmagic.comwww.xe.comIf I change the gatewy on those computer so they use the other Netgear router, it works, they cannot access those websites.
when Tracing Route from the SME server, tracert does NOT complete.
[root@sme2 lists]# traceroute

When doing a tracert with client using the Netgear gateway, tracert works:

I have Dansguardian working on the SME ...
When trying to access those 2 websites with client computer using SME as a gateway, nothng appears in the access.log file ... When accessing other "working" website, access.og file shows the connections.
Other info ...
For the SME, nslookup
www.textmagic.com DOES work.
Ping does
NOT work. via SME but DOES work via Netgear gateway ...
Very strange situation ... No changed have been made over the week-end on the SME server ... Everything worked well last week ...
I don't know this is related, but when trying to run "yum update" on the SME server, I get the following:
[root@sme2 lists]# yum update
Loading "smeserver" plugin
Loading "protect-packages" plugin
Loading "fastestmirror" plugin

I also get a email every night:

Cannot open/read repomd.xml file for repository: base

Error: failure: repodata/repomd.xml from base: [Errno 256] No more mirrors to try.
I should also mention a problem sending message from the SME server since yesterday. I had about 400 messages stuck in the queue ...
To bypass the issue, I had to use my IPS SMTP service ...
This might also be related.
the qmail log was showing a lot of lines like this:
delivery 519270: deferral: Sorry,_I_wasn't_able_to_establish_an_SMTP_connection._(#4.4.1)/
Any suggestions would be appreciated.
Thanks
