I have a setup as shown below.
Internet clients --> Site A FW--> Site A L3 Switch -->L3 Switch Site B--> Servers
Site B has a default route pointing to another FW at SiteB. I have to enable NAT on FW of SiteA in order in order for internet clients to reach to my server at SiteB is there a way where in i can do a config on SiteB L3 device so the reverse traffic for internet reaches back to SiteA FW and i don't have to NAT the connection on SiteA FW. I hope i am making sense to you guys. I have attached the diagram of network also.
L3 model at both site is cisco 3750 switch
