Hi All,
I am sure I've simply overlooked something but have a Cisco 877 that is connected to Provider A (Dialer1), Provider B (Ethernet - VLAN2) and LAN (VLAN1). Vlan1 is configured for ip nat inside, Vlan2 ip nat outside. Static routes have been added to direct a number of subnets to Provider B.
A trace from something on the LAN destined for one of the specific subnets looks right, goes out Provider B. Thats it though, if I hit port 80 on one of those IP's, tcpdump on the far side clearly shows the traffic is coming from Provider A IP Address (Ie. It took the default route out Dialer1)
This shouldnt be the case, the far side should see the request come from my Provider B address (Not that I believe its of relevance but provider B is a NAT'ed connection so I should not be seeing an IP assigned to my 877 but one within their network).
It was suggested its possible the NAT table still had current sessions but I have cleared this to no avail.
Does anyone have any thoughts? Can post a full config if needed.
Thanks in advance.

Config is attached (Less anything that can identify me / services).
Per the attached anythng destined for 119.1.1.0/21 should go out Provider B. This is the case with a trace but if I attempt to hit a service on a IP in that /21 the far side sees the request from the IP on Dialer1.
Thanks.
