Did some more reading up on the part I've not used i.e. squid tos marking. Looks like it supports only blanket outgoing tcp TOS marking without any rule based support. What I listed out will not work then. Alternative: 1. Ditch Squid and go for a simple gateway based solution. 2. Write ip rules to identify connections from s1 or s2 and direct them for lookup to tables t1 and t2 respectively.
