Is it possible to estabish tagged communication (using tagged ports and frames) between router 1841 and LAN switch (for example Allied Telesn 9924)to send and receive frames to a few vlans defined on switch over one physical link?
Switch can support tagged ports and frames but I don't know if router can.
you have to create sub-inbterfaces on the router for which you want the inter-vlan routing or even to have vlan go to the internet. In that case vlans will be able to talk to each other. use router ACL's to deny the traffic from one vlan to another vlan.

interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
