Need help interpreting tcpdump output line


I am running an ipchains firewall / router from my bband modem to a home network. The firewall / router is natasha, and caches DNS info to short-stop requests to Comcast (provider).

I am troubleshooting the loss of service I've experienced in a banking function (upon thier upgrade of software). This service tries to hand off my web session to a url that my browsers never connect to, timing out and failing.

When I remove the firewall completely, the service works. When I re-establish my FW and flush my chain filters and replace rules with "allow anything to anybody with a policy of ACCEPT) --- the service still fails.

Here is the tcpdump line that I am unable to interpret:

Code:
18:03:26.828178 192.168.1.1.1042 > natasha.domain:  3550+ A? webbill.bank.com. (38)
[ I have changed the actual url to webbill.bank.com for security reasons. ]

What is the 3550+ A? annotation?

Thanks,

Walt
