My 5505 drops me off Blizzard games (World of WarCraft and Overwatch) every half hour or so but not based on play time. For example, earlier today I was playing WoW. I got disconnected from the game every hour and half hour on the clock around 4-7 minutes and again at 34-37 minutes. If I connect to a Blizzard game, I'll be able to play until one of those times on the clock comes back around again (5:35, 6:04, 6:37, etc.). It doesn't seem to be exactly every thirty minutes as it's started happening a bit later in the hour every day.
When I'm directly connected to my cable modem, I don't experience the issue. Once the 5505 is introduced though, the issue returns. Additionally, whether I have multiple other devices on my inside LAN connected to the ASA doesn't seem to make a difference. The issue happens when the ASA is connected to just my PC and the modem.
I don't notice a problem with any other services, but there may be and I just haven't noticed it yet. The only thing that I can see that's likely related to the issue is that if I have Wireshark running when the issue happens, I seem to get a lot of RST, ACK from the Blizzard IP addresses.
I'm running 9.24 on the ASA.
Any help would be appreciated.
I confirmed that the issue does not happen when I'm directly connected to my cable modem.
Anyone have any ideas on how I might continue troubleshooting?
The problem seems to have cleared up on its own. The RST, ACK commands make me think it was a problem on Blizzard's end, but it seems weird that they were able to tell when I was using the firewall...
