I was trying to ping ensembl, which produce the results given below,
PING ensembldb.sanger.ac.uk ( 56(84) bytes of data.
From icmp_seq=5 Packet filtered
From icmp_seq=6 Packet filtered
From icmp_seq=9 Packet filtered
From icmp_seq=12 Packet filtered
From icmp_seq=15 Packet filtered
--- ensembldb.sanger.ac.uk ping statistics ---
17 packets transmitted, 0 received, +5 errors, 100% packet loss, time 36186ms

Is this normal, that I do not receive any packets back, I also wanted to query their MySql database which produce an error

"ERROR 2003 (HY000): Can't connect to MySQL server on 'ensembldb.ensembl.org' (111)"

are both of these related, I use a wireless internet connection (eduroam at my university), the LAN works perfectly, can this be a problem of my ubuntu firewall.
Any help would be highly useful for my research.
