SBS2008+Cisco ASA 5505, some computers cant use internet
Posted on 2011-10-28
Last week I installed a new firewall (Cisco asa 5505 10 users). We only have 7 computers here and like 6 cisco IP phones.
I think the problem begun after I installed the new firewall. Some computers here can't use the internet. Sometimes it works, and sometimes it dont. Everything under ipconfig /all seems just fine. Its exacly the same IP conf for the computers who can use the internet and for those who cannot.
I've opened the ports in the firewall that SBS2008 use (SSL,HTTP,HTTPS, and remote work place port)
I first thought it was the DNS server how gave me trouble, but then I tested to do a NSlookup and it worked just fine.
Right now we only have three computers on, and internet only works for two of them (yesterday all three computers had internet, but like I said, sometimes it works, and sometimes not)
Can anyone please help me? I going crazy here..
