SAP Router string issue

Hi Team,

I had setup SAProuter and we are connecting our R3systems through router.

in sap logon pad router string if i enter /H/saprouterIP/H/ it is working fine, where as if i enter /H/saprouterIP/H/R3systemIP it is getting failed with error " Invalid data from server during route completion.

I tried with router string /H/saprouterIP/S/3299/H/R3systemIP/S/3200/H/ it is failing with same error. Please let me know what is the possible issue here.

below is the error log from dev_route in saprouter.
