Btw
I can see on the FW logs these blocks which is not familiar to me:
2008-04-20 20:44:35 notice Firewall ICMP redirect packet detected, ICMP
Type:5, DROP [count=2] 10.5.26.1 10.5.26.10 ACCESS BLOCK

Hi.
A new customer. SBS 2003, Exchange. DNS and DHCP on the server. I changed
the switches and Firewall HW on friday evening. Now I can receive mails from
Internet via OWA while logged on to the server. Don't know weather Outlook
clients can receive mail in LAN. I can't send mails to Internet by OWA while
logged on to the server. The FW should't block any LAN to WAN or LAN to LAN
traffic. I suppose that before the FW replacment the users were able to use
OWA both locally on externally in this way:
https://mail.maildomainname.com/exchange
Now it doesn't work anymore (page can't be found) , these works only locally
and can receive mails send from Internet:
https//serverslanIP/exchange
https://servername.domainname.local/exchange
It seems that there is no way to send mails anywhere else but to another
domaiuser while connected to LAN.
I can see that there is one SmallBusines SMTP Connector set to forward all
mails though this connector to following smart hosts:
mail.ISPDomanname.fi, but I don't belive that it is actually in use.
Wonder what is the problem since I didn't make any changes to server?
Any ideas, please? I suppose there is no ISA in this server.
Thanks,
Juha
